The following is a list of rock types recognized by petrologists.There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types.

Rock synthesis. The synthetic investigation of rocks proceeds by experimental work that attempts to reproduce different rock types and to elucidate their origins and structures.

Rocks, also known as stones, are natural substances that are solid aggregates of several minerals. For instance, granite, which is a type of rock, is made up of biotite, quartz and feldspar minerals.

More information about specific rocks and minerals. Feldspar Feldspar refers to a group of minerals containing aluminum and silica.They all show good cleavage in two directions at about 90 degrees.
Abutment — In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back ...

A road sign in Newfoundland. How Do We Know That They Are Meteorites? On a broken or sawn face, all lunar meteorites look like some kinds of Earth rocks, even to an experienced lunar scientist.
See the various kinds of energy, kinetic, chemical, gravitational potential, electrical, sound, heat or thermal energy, together with energy transfer, energy stored and energy dissipation.
Metamorphic rocks are one of the three types of rock classifications, the other two being igneous and sedimentary.
This diagram shows the main groups of igneous rocks, their main mineral constituents and their intrusive (cooling in the crust) and extrusive (cooling as lava flow) equivalents.
INTRODUCTION AND DEFINITION . Below a thin, ragged mantle of soil and superficial material, the Earth's outermost shell is made up of rocks Most of these rocks are in turn made up of minerals.
Igneous rocks get their name from the latin word for fire - igneus. The name is appropriate because these rocks are born of fire.
Available Elements. Since the ^chemical elements are the fundamental building blocks of all ordinary materials, including minerals, let's start there. Elemental abundances at and near the surface of the earth tightly constrain the range of minerals and rocks observed, not to mention the range of possible biologic processes.
