Geophysical surveys are a noninvasive reliable tool to improve geological models without requiring extensive in situ borehole campaigns. The usage of seismic refraction tomography (SRT), electrical resistivity (ERT) and data for calibrating is very appropriate define landslide body geometries; however, it still only used occasionally. We present here the case Spanish Pyrenees slow-moving landsl...

The Triassic Jiucaiyuan Formation is a vital oil and gas exploration target in the eastern part of Junggar Basin. In this work, cores, thin sections, particle sizes, conventional physical properties were analyzed order to understand sedimentary characteristics depositional model Beisantai Uplift clarify factors controlling reservoir development. results demonstrate that can be divided into seve...

The Eocene to Lower Oligocene deposits of the Penyu and Malay basins are formed by fluvial-lacustrine with marine influence in latter. sequence consists mainly siltstone, several intercalations fine-grained sand volcanic tuff. Based on well data, Mid-Upper sediments exist Basin deeper parts half grabens sub-basins. Hence, this implies age basin initiation at Mid-Eocene, rather than as tradition...

The study area is an oil and gas field that has a low resistivity reservoir zone in the Talang AkarFormation, South Sumatera Basin. composed of siltstone sandstone was depositedin shallow to transitional marine environment. aim this identify determine potential oflow reservoirs formation. data used include well log, mud core data(porosity, permeability, petrography), formation water analysis, b...

This study reconstructs the depositional conditions of ironstones within Chulym-Yenisey basin and assesses iron source. The detrital minerals studied deposits include quartz feldspar. authigenic are goethite, siderite, aragonite, dolomite, calcite, apatite, barite, pyrite. clay components chlorite group (possible chamosite), nontronite, kaolinite, illite, beidellite. Local bacterial sulfate red...

The upper Miocene to Pleistocene Shimajiri Group, composed mainly of siltstone and sandstone, occurs on some the Ryukyu Islands in southwestern Japan. This group is thought have been deposited a shelf-slope fore-arc basin setting before accumulation coral reef deposits (Ryukyu Group). We investigated calcareous nannofossil biostratigraphy Group Offshore Okinawa 1-x well, drilled near northeaste...

Changes in land use due to open pit mining operations, indirectly affect the hydrological cycle. Open especially method, greatly subsurface conditions, such as lithology and hydrogeology. The purpose of this study was analyze hydrogeological conditions before on syncline folds Mahakam river. This research is an inductive with analytical approach which includes use, geology, area dominated by pl...

The Lough Foyle Basin is a half-graben that straddles the border between Northern Ireland and Republic of contains sediments range in age from Lower Carboniferous to Holocene. basin’s post-rift succession represented by Penarth Group Lias Group. lithostratigraphy biostratigraphy interval are revised using new borehole material existing outcrop. Palaeontological data provide chronostratigraphic ...

A small skeletal fossil assemblage is described for the first time from bioclastic limestone interbeds of siltstone-dominated Guojiaba Formation, southern Shaanxi, China. The carbonate-hosted fossils include brachiopods (Eohadrotreta zhujiahensis, Eohadrotreta zhenbaensis, Spinobolus sp., Kuangshanotreta malungensis, Kyrshabaktella Lingulellotreta yuanshanensis, Eoobolus incipiens, and sp.), sp...
