Test Review: Chapter 1: - Formation of universe - Age of universe - Age of earth - Heliocentric vs. geocentric model - They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg (CO3)2] replaces the calcite and aragonite minerals in limestones during diagenesis.Intrusive igneous rocks—those that congeal at depth—are virtually always crystalline, whereas extrusive igneous rocks, or volcanic rocks, may be partly to entirely glassy. …

Noncarbonate chemical sedimentary …If non-clastic rocks are fine-grained enough, they too can be called aphanitic. Clastic sedimentary rocks are subdivided on the basis of grain size. Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition.

Clastic rocks are classified and named according to texture (clast size, sorting and rounding), and mineral composition. An important characteristic of the clastic sedimentary rocks, however, is that all have clastic textures. That is, the grains are not interlocking- they are held together as an aggregate by a cement. Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it is called shale. Otherwise, it is siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay). The photo seen here (Figure 7.25) shows a marble made of coarsely crystalline calcite. ... Many chemical sedimentary rocks contain clastic material, and many ...
See answer (1) Best Answer. Copy. A Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. A Bioclastic rock is a clastic rock but the fragments are ...Crystalline igneous rocks generally have three types of textures: aphanitic, phaneritic, and porphyritic (Figure B-1). Three additional textures are used with the extrusive igneous rocks, which are: glassy, vesicular and pyroclastic. Aphanitic textures consist of equigranular, small (fine-grained) crystals; phaneritic textures consist of ...Sedimentary rock - Clastic, Chemical, Organic: Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix. Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts are angular or subangular. Conglomerates are ...

Clastic sedimentary rocks are formed from rock fragments, or clasts; chemical sedimentary rocks precipitate from fluids; and biochemical sedimentary rocks form as precipitation from living organisms. Practice Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonate s (above figure).
