Percultalina n. gen. is introduced here to include the Early Paleogene benthic Lagenid foraminiferids from Jordan and Egypt (Southern Tethys) that characterized by its large lenticular initial portion followed by two or more uniserial elongate erected or inclined inflated rounded chambers, ornamented surface by elevated sutures with a row of tubercles or nodes along the sutures, and spinose surface. This new genus has been previously assigned to different genera: Vaginulinopsis Reuss, or Percultazonaria Loeblich & Tappan, or Marginulinopsis Silvestri. Three Early Paleogene species of the new genus are described here from two countries in Jordan: Percultalina wadiarabensis (Futyan) with rectilinear uniserial portion of the test (the genotype of the new genus), and Egypt: Percultalina misrensis Anan (n. sp.), and P. sinaensis with inclined uniserial portion of the test. Moreover, varied and diverse genera of the Lagenid benthic foraminifera are attempted here to study the holotypes of seven diagnostic genera of this group: Lenticulina Lamarck, Cribrolenticulina Haman, Marginulinopsis Silvestri, Percultazonaria Anan, Leticuzonaria Anan, Lenticubella Anan and Percultalina Anan. The taxonomic revision of these seven genera will greatly aid paleontologists and biostratigraphers to helpfully understanding.

Seismic refraction data was acquired in the Middle Benue Trough which is located in the north central Nigeria with latitude 07.5-08.5oN and longitude 08.00-09.30oE. The aim was to find out how velocity vary in the near-surface layers in the area using seismic refraction data. The seismic survey was investigated at 14 acquisition stations. Two overlapping reversed profiles were shot into 14 stations. Each acquisition station was primed with 0.20kg dynamite loaded at 1.5m below the surface. The recording equipment was McSeis-160MXTM, and monitor record was processed with Microsoft Excel software to determine the velocities from both the forward and reversed shot-points. The results show two distinct layers cases. The thickness of the topmost layer varies between 2.75m and 5.45m with a mean of 4.1m. The velocity of this topmost layer varies between 399.0 ms-1 and 767.0ms-1 with a mean of 604.8ms-1. The velocity of the underlying layer (V1) varies between 1212.5ms-1 and 3257.0ms-1 with a mean of 1757.9ms-1. The velocity increases with depth into the subsurface. The results are useful in locating groundwater aquifer, and in the design of source-receiver arrays for reflection seismic.

Lenticubella n. gen. is introduced here to include the Paleocene benthic Lagenid Foraminiferids from some Tethyan localities (Poland and Egypt) that characterized by symmetrical planispirally enrolled hyaline calcareous test in the early stage, followed by later uniserial stage, moderately involute chambers, smooth surface, radiate aperture, with periphery keeled in some individuals. Some representatives of the new genus have been previously assigned to the genus Darbyella, or Lenticulina, or Robulus. The new genus has a compiled characters between its lenticular test (as the genus Lenticulina Lamarck (with its symmetrical planispirally enrolled test, and smooth surface), and also another genus Darbyella Howe and Wallace (which has planispiral-uniserial test with inclined positon on the uniserial part on the early planispiral direction). Two Paleocene species of the new genus are described from Poland in the Northern Tethys (L. irregularis and L. polonica), and another two species from Egypt in the Southern Tethys (L. kurkurensis and L. misrensis). The Polonian species have flush or slightly depressed sutures, while the Egyptian species have raised sutures, mainly in the planispiral stage, but slightly depressed sutures in the uniserial stage.

Groundwater is a major source of water supply throughout the world. Its dependence is at the increase, so is highly necessary to ensure that there is a significant supply of potable water with high quality. On the verge of seeing these problems, we investigated shallow aquifer in Rumuohia community in Emohua local government area, Rivers State, Nigeria which aimed at utilizing seismic refraction method to delineate depth to shallow aquifer and geological structure of the terrain at five selected locations. The analysis of the result shows two layers with the presence of sand-gravel and clay lithologies. Layer 1 in all five locations is made up of clay with an average velocity of 274.83m/s with a thickness range of 4.88m to 9.98m at an average of 7m. Layer 2 in two locations is made up of sandy clay. In one location, it is clay while in the remaining two locations they are sand with gravel (dry), which infers a potential aquifer with an average velocity of 422.63m/s. The sand being present indicates a good aquifer, and clay serves as a stopper for the sand since it tends to go through compaction by overburden pressure. The study area is generally a good site for a borehole with a high tendency for potable water supply.

Field and petrographic studies of the Makenene area in the Central African Fold Belt in Cameroon reveals several features testifying the mafic and felsic magmas interactions and their coeval nature. They are: (1) the Mafic Magmatic Enclaves (MMEs) scattered throughout the Makenene granitoid pluton and displaying sub-rounded shape and back veining, (2) flow structures consisting of schlierens at the tails of MMEs, folded MMEs along with felsic host granitoids with hinge indicating the flow direction, (3) irregular or cuspate boundary between MMEs and host granitoids, (4) quenching of apatite and biotites minerals, (5) MMEs enclosing other MMEs or felsic host granitoids. The mafic magma injection operated during at least four stages (from early to late crystallization state of the host magma) leading respectively to the formation of homogenized granitoid; sub-spherical MMEs scattered in the pluton; dismembered dyke and undisturbed synplutonic mafic dyke. The Makenene area registered four deformation phases (D1 to D4). The first two deformation phases occurred before the magmatism and migmatization events. The third phase is coeval to the magmatism and the migmatization period (at the Eburnean orogeny (2.08-2.07 Ga)). The fourth phase is related to the Panafrican orogeny.

The present study is a part of the comprehensive works concerned with the complete record of the Paleogene small benthic foraminiferal content in the Ranikot and Laki Formations of the Nammal Gorge, Salt and Sor Ranges of Pakistan. The first part was concerned with the Miliolina and Lagenina foraminiferal assemblage of Haque from Pakistan, and followed by the second part which concerned with the Rotaliid assemblage of the same author of Pakistan. The third part is concerned with the Textulariid part and presented in this study. Twenty one Early Paleogene Pakistanian smaller Textulariid (Agglutinated) benthic foraminiferal species and subspecies from the Ranikot and Laki Formations of the Nammal Gorge, Salt and Sor Ranges of Pakistan have been studied and are systematically listed. This systematic description provides a list of modern synonyms, short remarks about morphological features, and some annotations about taxa with problematic generic status. These species are: Spiroplectinella ushbali, Gaudryina nitida, Siphogaudryina daviesi, S. elongata, S. nammalensis, Verneuilina laevigata, Tritaxia elongata, T. limbata, Dorothia nammalensis, Marssonella nammalensis, Bigenerina khirthari, B. metingensis, B. nodosa, Textularia crookshanki, T. haquei, T. punjabensis, Clavulinoides lakiensis, C. spatha, C. symmetrica, Valvulina n. nammalensis, V. nammalensis longa. Most of the recorded species are an endemic to Pakistan, except five species Siphogaudryina elongata, Tritaxia elongata, T. limbata, Textularia crookshanki and T. punjabensis are recorded in some Northern Tethys (France, Hungary) and Southern Tethys (India, Iran, UAE, Egypt, Algeria). The paleoenvironmental interpretations of the identified species in the study area of Pakistan were deposited in somewhat deep water and open-marine environments. The abundance of pelagic Pakistanian benthic foraminiferal assemblages indicate an open connection to the Tethys, which represents middle-outer neritic environment (100-200 m depth) and shows an affinity with the Atlantic-Tethyan Regions: “Midway Type Fauna “.

Sangon Hamlet is included in the mountains which are dominated by andesite rocks and volcanic breccias which cross each other and have a distribution of joints and faults forming a fracture. The fracture is a medium for draining water in the area. There is a difference in ground water level as seen from the well. To re-detail the groundwater flow that has been formed, a groundwater flow pattern modeling is carried out. The modeling is done by numerical method assisted by Modflow Flex Software. For building the model, it is necessary to prepare a concept model, calibration and validation. In this area there are 2 aquifer systems, namely unconfined aquifers and aquitards. Furthermore, the model was calibrated using the sensitivity analysis method. The calibration results are obtained, namely the RMS value of 8.74% with a standard error estimate of 1.27 m and a correlation coefficient of 0.98. From this model, it is known that the flow of water moves from the northwest-north area in the form of a plateau by heading to the east-southeast area which is a lower plain and towards the Plampang River.

Study area concedes the compressional stresses caused by the collision of Indian and Eurasian plates molded the northwest- southeast trending faults which are Riasi Fault (RF), Palandri Fault (PF), Godri Badshah Fault (GBF) and Chhechhan Fault (CF). This study intended to analyze the Kamlial sandstone as an aggregate problem for construction industry while sedimentary structure, stratigraphic sequence and geology of the study area were also destined. The study area comprised Nakar, Chhechhan, Holar, Tallian and Sarsawah of Palandri Azad Kashmir. The Impact value, Los Angeles Abrasion resistance, Specific gravity and Water absorption test were evaluated for kamlial sandstone. The samples were collected from Garata Sarsawa, Panjeera, Telyan, Kharran, Jabbri kass, Kand Gora, Parasgali, Garrala, Hollar, Chhechann and Nakar near Pallandri. Impact value of Kamlial Sandstone recorded 25.2, Abrasion Resistance of Kamlial Sandstones is 41.4 % which is less than AASHTO value i.e 50 percent. The Apparent Specific gravity initiate 2.1 percent which is less than ASTM standards i.e between 2.6-2.9. and the Water Absorption value recorded 2.24%. The results intimate that the Kamlial sandstone does not qualify ASTM specification for aggregate.

Eighty-five Early Paleogene Pakistanian smaller Rotaliid benthic foraminiferal species belong to thirty-nine genera from the Ranikot, Nammal and Laki Formations of the Nammal Gorge, Salt and Sor Ranges of Pakistan have been studied. The modern taxonomic consideration and systematic description of the species is based on the diagnostic morphology, list of synonyms, short remarks about morphological features, and annotations about taxa with problematic generic status. Most of the recorded species are, so far, an endemic to Pakistan, except 19 species of them were recorded in other localities in the Southern Tethys (India, Qatar, United Arab Emirates, Saudi Arabia, Egypt, Nigeria) and also in Northern Tethys (France, Spain, Slovenia). The high abundance of pelagic Pakistanian foraminiferal assemblage indicate open connection to the Tethys, which represents middle-outer neritic environment (100-200 m depth) and shows an affinity with Midway-Type Fauna ‘MTF’.

Ramsar sites are important habitats for the locals as well as for migratory birds that visit these sites across the borders every year. Langh and Drigh lakes were selected as the study area for this research. Drigh Lake is one of the important Ramsar sites, and Langh Lake is an important wildlife sanctuary of national importance. For the past few decades, these lakes are degrading due to anthropogenic activities. To quantify these variations, present study was carried out to detect the land use and land cover change in these lakes and their surrounding areas from 1988 to 2020. Level-2 imageries of Landsat 5, 7, and 8 were downloaded and analyzed using hybrid classification, and results were mapped in ArcMap. Accuracy assessment of the results of selected years was done to check the accuracy of results using the Kappa coefficient. Kappa coefficient resulted between 0.82 and 0.95 for this study. Classification results depicted a significant increase in the vegetation area which is 72% and 32% for langh and drigh lakes respectively since 1988. Results show an increase in the buildup area and a decrease in the barren land. The presence of dense vegetation in the lakes near their boundaries verifies encroachment of lakes by the local farmers.
