[1] We collected 56 marine gravity cores from the Pacific seafloor offshore Central America which contain a total of 213 volcanic ash beds. Ash-layer correlations between cores and with their parental tephras on land use stratigraphic, lithologic, and compositional criteria. In particular, we make use of our newly built database of bulk-rock, mineral, and glass major and trace element compositi...

Introduction: Lunar meteorite Dhofar 961, a complex, lithic-clast-rich impact breccia [1,2], was called out by [3-6] as a candidate for an origin in the South Pole – Aitken (SPA) Basin region of the Moon (the SPA Terrane) on the basis of its relatively mafic, but nonmare lithologic and major-element chemical composition. It also has an incompatible-element signature that differs from the KREEP-...

Abstract The floodable volume of longwall gob can be great importance in developing accurate coal mine operation plans, particularly for water management and environmental control strategies. Given the inaccessibility difficulty direct measurement characteristics following recompression, hydrologic, geomechanical, spatial data principles were used to solve porosity height residual using a mathe...

Understanding the interaction between tectonics, climatically-driven surficial processes, and bedrock erodibilityprovides insight into how landscape develops over space time. Although numerous active faults, lithologicand climatic variability control across Northern Thailand, influence of these factors on thespatial adjustment a dynamic is largely unknown. In study, we focus lower-order channel...

investigating downstream changes in bed load shape can be useful to detect watershedhydrological processes and it is very important to design hydraulic structures and to managecapacity of large storage dams, properly. regarding to doing of enforcement studies, thisresearch was conducted in qalesar river in upstream of chahardangeh watershed in mazandaranprovince. after recognition of the study ...

The Quiricó Formation presents an abundant and diversified fossil record, is the only formation from Cretaceous of São Francisco basin with occurrence ostracodes. This was described banks creek, tributary Prata river, which type locality. However, a stratotype section not described. present work description proposal hypostratotype section, based on lithologic fossiliferous occurrences. studied ...

The study aims to determine the hydrologic properties of an aquifer Malamawi Island in terms transmissivity, storage coefficient, and specific discharge using Theis method. was conducted March 2015. 4 inches 2- boreholes are drilled two different locations (Diki Santa Barbara villages) identify lithologic properties. A pumping test performed for forty-five (45) minutes and, drawdowns observed f...
