What Does The Name Feldspar Mean

The feldspars are essential constituents of nearly all crystalline rocks as granite gneiss mica slate most kinds of basalt and trachyte etc. The decomposition of feldspar has yielded a large part of the clay of the soil also the mineral kaolin an essential material in the making of fine pottery.

Pyrite Mineral Uses and Properties

Oxidation of pyrite can result in damage to pavement foundations and floors. In parts of the country where pyrite is commonly found construction sites should be tested to detect the presence of pyritic materials. If pyrite is detected the site can be rejected or the problem materials can be excavated and replaced with quality fill.

Swelling behavior induced by alteration in granite and its

Granite is commonly recognized as an ideal medium for underground construction. However in the site investigation for Heimifeng Pumped Storage Power Station project it was found that there are swelling behaviors induced by alteration in granite and eventually causing slaking and disintegration of rock blocks.

SappingWikipedia

Sapping is a term used in siege operations to describe the digging of a covered trench (a "sap" ) to approach a besieged place without danger from the enemy s fire. The purpose of the sap is usually to advance a besieging army s position towards an attacked fortification. It is excavated by specialised military units whose members are often called sappers.

SithathoriunetWikipedia

Sithathoriunet (her name means "daughter of Hathor of Dendera") was an Ancient Egyptian king s daughter of the 12th dynasty mainly known from her burial at El-Lahun in which a treasure trove of jewellery was found. She was possibly a daughter of Senusret II since her burial site was found next to the pyramid of this king. If so this would make her one of five known children

FeldsparWikipedia

Feldspars (K Al Si 3 O 8Na Al Si 3 O 8Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41 of the Earth s continental crust by weight.. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known

Phosphate and feldspar mineralogy of equilibrated L

In this study we focused on feldspar within chondrules which is largely formed from the devitrification of chondrule mesostasis and should share a similar history of development throughout the chondrite. We do not consider feldspar found within the chondrite matrix because limiting our observations to chondrule‐hosted feldspar allows for a

Geology of the MoonWikipedia

The geology of the Moon (sometimes called selenology although the latter term can refer more generally to "lunar science") is quite different from that of Earth.The Moon lacks a significant atmosphere which eliminates erosion due to weather it does not have any known form of plate tectonics it has a lower gravity and because of its small size it cooled more rapidly.
