Effects of salinity and sand content on liquid limit and hydraulic conductivity

Soil conditions of construction sites have become worse than ever due to the overpopulation in the metropolitan areas throughout the world. Likewise, the

Biostratigraphy, mineralogy and geochemistry of the Trabakua Pass and Ermua sections in Spain : Paleocene-Eocene transitions

Isotopic, geochemical and bulk mineralogical analyses in the Trabakua and Ermua sections, Basque Basin, reveal major changes across the Paleocene-Eocene transition. Expanded sedimentary records

A new look on the Jurassic formations of the western part of Iraq

The Jurassic succession of western Iraq includes the Ubaid, Hussainiyat, Amij, Muhaiwir, and Najmah formations. Each formation is composed of basal clastic unit overlain by upper carbonate unit.

Sepiolite-Palygorskite from the Hekimhan Region (Turkey)

Upper Cretaceous-Tertiary marine clayey-calcareous rocks of the Hekimhan basin contain fibrous clay minerals in significant amounts. Ophiolitic rocks in the provenance area have contributed the

Clay Mineralogy of the Wadi M’Goun Sediments, Their Source, and Distribution on the Southern Flank of the Central High Atlas Mountains (Morocco)

Abstract Clay minerals are regarded as the most critical chemical and weathering components in ground. To establish the origin and distribution of the clay mineral associations of the Wadi M’Goun

Latest Miocene (Kapitean/Messinian) glauconite and the central Chatham Rise greensand: an enigmatic, highly condensed, relict/palimpsest deposit on the modern seafloor

ABSTRACT A unique 10–140 cm thick veneer of greensand and glauconite-rich deposits (10–80 wt% glauconite) presently sits atop central Chatham Rise (CR) in water depths of 200-500 m. The glauconite is

The fluctuation of warm paleoclimatic controls on lacustrine carbonate deposition in the Late Cretaceous (late Santonian), Southern Songliao Basin, Northeast China

During the Cretaceous, a high global sea level and low latitudinal temperature variations led to the growth of epeiric supergene carbonate platforms. Lacustrine carbonates are widely developed within



Genesis of Clay Minerals: Inheritance and Transformation

Throughout the expose of facts three principal processes have been invoked to account for the genesis of clay minerals: Detrital inheritance; Transformations; Neoformations.

Superficial Geochemistry and The Silicate Cycle

By a slow process clays have been described in their deposits and then in the mechanisms of their formation. It is instructive at the end of this process to consider the whole problem in geochemical
