What are some properties of Dolerite? | Yahoo Answers

It has a fine-grained diabasic texture (figures 1 and 2). The plagioclase is shock melted. The pyroxene is more homogeneous than for other shergottites (figure 3). Besides olivine, pyroxene and plagioclase, it has chromite-ulvospinel, pyrrhotite, merrillite and rare magnetite. Mineralogy. Olivine:Olivine is Fo.

Diabase is composed of plagioclase feldspar (mostly labradorite) and pyroxene ().The crystals that make up dolerite are usually visible to the naked eye, but sometimes porphyritic rocks of basaltic composition with pyroxene and especially plagioclase phenocrysts are also named that way. Ophitic texture (randomly oriented plagioclase laths enclosed by pyroxene grains) is a characteristic ...

This textural sequence is typically found at the margins toward the center in diabasic or doleritic rocks (basaltic dikes) or from the chilled surface to depth of basaltic flows. If the cooling rate is very fast, the interstitial material between plagioclase laths may be quenched to glass to form an intersertal texture…

Aug 01, 2013· The diabase exhibits typical diabasic texture and is composed of plagioclase (up to 50%) and augite (40–45%) with subordinate hornblende (less than 5%), brown biotite (less than 5%), magnetite (1–2%), apatite and diposide (Fig. 3b). In several thin sections plagioclase phenocrysts (less than 5%) are observed.

Ophitic texture is the association of lath-shaped euhedral crystals of plagioclase, grouped radially or in an irregular mesh, with surrounding or interstitial large anhedral crystals of pyroxene; it is characteristic of the common rock type known as diabase.
