  In simple terms, hard rock scratches glass and steel, usually signifying the minerals quartz or feldspar, which has a Mohs hardness of 6 or higher. Soft rock does not scratch steel but will scratch fingernails (Mohs scale of 3 to ), while very soft rock .   Explore Activity: Exploring Properties of Rocks Students describe the properties of different types of rocks, and classify the rocks into groups. Materials list, advanced preparation instructions, lab hints and tips, rubric, worksheets, and answer key are provided.

  3. engineering properties of rock [email protected] 3 Extrusive Rocks: Extrusive rocks are found in crystalline texture. The origin of these rocks are greatly influence their engineering properties. Main characteristics which influence the engineering works are followings. Variable composition and texture. Strength durability and permeability. Types of Rocks in India. Following are the classification of rocks in India: Rocks of the Archaean system: These rocks get this name as they are formed from the hot molten earth and are the oldest and primary is an example and is found in Karnataka, Andhra Pradesh, Tamil Nadu, Madhya Pradesh, Orissa and some parts of Jharkhand and Rajasthan.

The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well -known point load strength index can be useful as the.

Abstract. Rock physical and mechanical properties are very important parameters for geological engineering design and construction. For instance, in coal mining industry many geological disasters induced by mining were associated with misunderstanding of rock mechanical properties (Peng a, Han and Peng ).

After a brief introduction to the Rock Cycle, this text presents the physical properties of minerals and an introduction to crystallography.

The most important rock-forming minerals are then dealt with in a systematic way, followed by the three main rock groups – igneous, sedimentary and metamorphic. The five physical properties of rocks are color, luster, shape, texture and pattern. Not all rocks have the fifth property of pattern.

These properties are visible and/or tactile. Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth. Learn more about the properties and uses of granite in this article.

Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins.

As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic.

• The key question with regard to rock slopes along highways is their long- term stability since failure of a rock slope can have serious consequences. • The stability of a particular rock slope is • governed by three main engineering geologic factors. By knowing what properties are critical to performance, meaningful predictions can be made in blast design.

These properties are: detonation velocity, density, detonation pressure, water resistance, and fume class. For a given explosive, these properties vary with the manufacturer. (Figure ) The mechanics of blasting. Friction in Rocks.

Helium-3 (3 He, tralphium, see also helion) is a light, stable isotope of helium with two protons and one neutron (the most common isotope, helium-4, having two protons and two neutrons in contrast).Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons.

Helium-3 was discovered in Geophysics (/ ˌ dʒ iː oʊ ˈ f ɪ z ɪ k s /) is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term geophysics sometimes refers only to geological applications: Earth's shape; its gravitational and magnetic fields; its internal.

The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification.

Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties.

If we take the definition of a mineral term by term, it becomes easier to understand.Physical properties of materials and systems are often described as intensive and extensive properties.

This classification relates to the dependency of the properties upon the size or extent of the system or object in question. An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on.
