What is Basalt Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin has a composition similar to difference between basalt and gabbro is that

— The amount and chemical composition of the matrix If the clasts do not touch each other lots of matrix the rock is paraconglomerate Rock in which the clasts touch each other is called orthoconglomerate The environment that deposited the material Conglomerates may form from glacial alluvial fluvial deepwater marine or shallow

Depending on size clasts may be boulders cobbles pebbles gravel sand silt or clay The word clay sometimes causes confusion Sedimentary petrologists use the term to refer to clastic grains smaller than mm in longest dimension Both of these are zeolite minerals that occur most commonly in openings within basalt and less

— There are three main types of rocks sedimentary igneous and metamorphic Each of these rocks are formed by physical changes—such as melting cooling eroding compacting or deforming —that are part of the rock cycle Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic

— Basalt stone tools were collected from some Iraqi Archaeological Sites Twenty one samples were studied petrographically mineralogically and chemical composition
— The average ε 123 Sb value of basalt was ε and the variation range of ε 123 Sb of the profile sample was −ε to ε with ZJ 12 m depth showing the most positive ε 123 Sb value of ε Except for ZJ 12 the isotopic compositions of Sb in the soils were lighter than those of the basalt Strong leaching of alkali and alkaline earth

— Gabbro is a type of intrusive igneous rock that is coarse grained and dark colored typically composed of calcium rich plagioclase feldspar pyroxene and sometimes olivine It is similar in composition to basalt which is its extrusive equivalent Gabbro is typically found in plutonic bodies such as batholiths and dikes and is often associated

The coarse and medium grained equivalents of basalt are gabbro and dolerite respectively Basalt is distinguished from pyroxene andesite by its more calcic plagioclase There are two main chemical subtypes of basalt tholeiites which are silica saturated to oversaturated and alkali basalts that are silica undersaturated Tholeiites dominate the

Clastic Sedimentary Rocks Detrital Clastic sedimentary rock also called detrital sedimentary rock consists of sediment pieces clasts/rock detritus that come from weathered bedrock cemented together to make a new rock The clastic sediment is often referred to as siliciclastic because it is derived from the rocks of the crust which as we
