The Albitization of K-Feldspar in Organic

The albitization of K-feldspar is a common diagenetic process that has thus far received little attention and is not fully understood in fine-grained sedimentary rocks. To better understand the albitization of K-feldspar, studies in organic- and silt-rich fine-grained rocks of the lower Cambrian Qiongzhusi Formation in the southwestern Upper Yangtze region, China, were carried out via X-ray ...

Analyzing grain size distributions with the modal ...

2021-7-7 · Many studies describe soil samples by their grain/particle size distribution (GSD/PSD). Most samples are poly-disperse collections of solids. The paper reviews earlier methods to describe or fit a GSD: usually, their R2 value is in the 0.5–0.9 range. A modal decomposition method (MDM) was developed to extract from a GSD its sub-populations or modes, proportions, and specific surface area ...

2015-10-5 · Adding a small amount of non-plastic silt to clean sands may lead to dramatic loss of shear strength and a noteworthy tendency toward contraction when the mechanical behavior of the mixture is compared with that of the clean host sand. Thus, simulation of the behavior of silty sands with varying fines content is still a challenging subject in geomechanics. A unified constitutive model for ...
