Shale mineralogy

Shale is mostly made up of clay, so it can range in color from medium brown to white. Shale is often used to make ceramic tiles. Shale colors fall in the neutral color palette and can be paired with blues for a country look, soft pinks for ....

The Haynesville Shale is an informal, popular name for a Jurassic Period rock formation that underlies large parts of southwestern Arkansas, northwest Louisiana, and East Texas. It lies at depths of 10,500 to 13,000 feet below the land’s surface. [1] [2] It is part of a large rock formation which is known by geologists as the Haynesville ...Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals 4) and tiny fragments of other minerals, ...The accurate identification of shale lithofacies is key for exploration and development.

Table 1 shows the detailed results for mineral content (as ranges) in the Longmaxi Shale samples. More than 10 minerals were detected in the Longmaxi gas shale. The main minerals in the Longmaxi Shale are classified into four groups: quartz, feldspar, carbonate and clay minerals. Albite, oligoclase, and orthoclase are included in the feldspars.The high TOC content and brittle minerals within chemozone C1 makes it the most preferable layer for shale gas exploration and development.However, microstructural images of shale at high-resolution, obtained through scanning electron microscopy (SEM) are constrained in the two-dimensional (2D) scale.Method: In … ….
