In recent decades, lithological mapping techniques using hyperspectral remotely sensed imagery have developed rapidly. The processing chains visible-near infrared (VNIR) and shortwave (SWIR) data are proven to be available in practice. thermal (TIR) portion of the electromagnetic spectrum has considerable potential for mineral lithology mapping. particular, abovementioned rocks at wavelengths 8...

The fate of phosphorus (P) during pedogenesis has been historically conceptualized (Walker-Syers model) with time as the primary controlling state factor. Herein, we demonstrate that both climate and lithology exert a strong interacting influence on P by examining coupled bioclimatic parent material effects soil fractions. Three transects were investigated spanning 2150-m elevation gradient (MA...

Natural fractures act as critical flow channels and reservoir space in the Lucaogou Formation tight of Jimsar Sag. It is essential to identify main controlling factors natural order achieve efficient development oil this area. There are mainly three types fractures, including tectonic diagenetic abnormal overpressure-induced fractures. Diagenetic predominantly bedding seams. The fracture affect...

In recent years, borehole Stoneley wave amplitude and reflectivity have been used for estimating formation permeability based on the strong correlation between Stoneley wave attenuation, reflectivity and formation fluid conductivity. There are other factors, however, that may cause substantial Stoneley attenuation and reflection in a borehole environment. To make better use of Stoneley measurem...

To predict erosion rates throughout the Andes, we conducted a multiple regression analysis of the sediment discharge from 47 drainage basins in the Bolivian Andes and various topographic, climatologic, and geologic parameters. These mountainous basins are typically large (17–81,000 km; km), often have decades of measurement mean p 11,000 data on daily water and sediment discharge, and display a...
