Limestone SlideShare

May 21, 2012· LIMESTONE ROCKS LIMESTONE CHALK 2. Limestone Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Many limestones are composed from skeletal fragments of marine organisms such as coral or CAco3 Molecular Structure foraminifera.

Hydrothermal Alteration of Limestone and Mineral

Abstract: Crystalline limestone of the Sako‐nishi area in the Kamioka Zn‐Pb mine, central Japan, is depleted in 18 O and 13 C toward the center of mineralization due to interaction with hydrothermal fluids with a dominant meteoric water component. The relationship between isotopic composition and mineral assemblage, texture, the chemical composition of the minerals, and the bulk chemical

Dolomite (Mineral) an overview ScienceDirect Topics

Carbonate rocks are also a class of sedimentary rocks that are composed primarily of carbonate minerals. The two major types of carbonate rocks are limestone (CaCO 3) and dolostone, primarily composed of the mineral dolomite (CaMg(CO 3) 2). Carbonate rocks can be of various origins like: • Detrital, which are formed of debris of limestone

Lecture 9 Introduction to Rock Strength David Hart

• The peak stress is the strength of the rock. It may fail catastrophically if the load frame is “soft”. Example below is for a “stiff” frame. • The compressive strength of rock is a function of the confining pressure. • As the confining pressure increases so does the strength.

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets,the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under

Carbonate Rock an overview ScienceDirect Topics

Outside China, source rocks in carbonate oilfields are mainly marine clastic rocks with TOC contents higher than 0.5% and mud-rich, carbonate rock with abundant organic matter (Xia and Dai, 2000). The carbonate source rocks are generally marlite and argillaceous limestone. Pure carbonate rock is less capable of generating hydrocarbons.
