Jan 30, 2008·Limestoneis a sedimentary rock formed by chemical and bio chemical action. It is composed of calcite which is relatively soft mineral (3 on mohs hardness scale). It will fizz when it comes in contact with acid and can be easily scratched by a steel nail or glass.Basaltis an igneous extrusive rock formed when lava extrudes out of the earth.

Feb 25, 2009· How can you distinguish between abasaltand afine grained limestone? Answer Save. 1 Answer. Relevance. busterwasmycat. Lv 7. 1 decade ago. Favorite Answer. I can tell by looking at them. They are really not very similar. However, you can tell by hardness or reaction with acid.Limestoneis much softer and of course the carbonate that is ...

Basalt:Fine-GrainedMafic Rock. Basalts may be entirelyfine grainedor may show phenocrysts of olivine and/or plagioclase. Basalts also may show vesicular or amygdaloidal textures. This rock displays afine-grained, porphyritic texture. The relatively small olivine phenocrysts are more clearly displayed in the close-up photo below.

Sometimeslimestonecan also look likebasalt- when it has small amounts of carbon it too isfine grainedandblack. Spectroscopy allows scientists to recognize different types of rocks that may initially look or feel the same, or which are too far away to be touched at all, based on subtle differences in how material reflects light across a ...

Shale is afine-grainedsedimentary rock which is formed by the compaction of silt and clay-size mineral particles.Basaltis a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth.

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 sill has a composition ...

BASALTis a volcanic rock composed of feldspar and ferromagnesian minerals.Fine-grainedand dark-coloured,basaltis a very strong stone and is suitable for flooring, wall cladding, countertops and also fireplace surrounds. The stone is suitable for either exterior or interior applications.

Difference BetweenBasaltand Granite | Difference BetweenBasaltis an igneous, mafic, and volcanic rock which is produced by lava flows in many different volcano types. It contains mainly volcanic glass, pyroxene and plagioclase feldspar and isfine-grained. Get price

Limestoneis composed of calcium carbonate (CaCO 3), thought to originate from the carbonate-based shells and skeletons of tiny sea creatures.Limestonecan range from chalk-white all the way through dark gray to almostblack. This darklimestonelooks likebasaltor "traprock" at first glance, but it is much softer and is easily attacked by acids.

fossiliferouslimestone. Fossiliferouslimestoneis any type oflimestone, made mostly of calcium carbonate (CaCO 3) in the form of the mineralscalcite or aragonite, that contains an abundance of fossils or fossil traces.The fossils in these rocks may be of macroscopic or microscopic size. The sort of macroscopic fossils often include crinoid stems, brachiopods, gastropods, and other hard ...

Limestone.Limestoneis afine-grained, sedimentary rock formed from compressed and cemented seashells and marine animal skeletons. Due to a large number of minerals in its composition,limestonecan vary in colour from cream to pink to brown toblack.

Fine-grainedtextures generally indicate magmas that rapidly cooled at or near the Earth's surface. Fast cooling prevents crystals from growing very large. The cutoff betweenfine- and coarse-grainedtextures is about 1 mm. All four photos below are of the mafic rockbasalt. The more felsic ...

siltstone – afine-grainednon-carbonate clastic rock composed of at least 67 per cent of detrital grains of quartz and silicate minerals of silt size. Siltstones are rarely marketed as such but commonly are considered asfine-grainedsandstones. This class of sediments is texturally transitional between sandstones and shales (mudstones).

Further offshore, away from sandy areas, finer-grainedsediment accumulated and chemical sediment precipitated to formlimestoneand a closely related rock called dolostone. In this environment, marine life was abundant. Shells and skeletons of various clams, snails, corals, and other animals are preserved in thelimestoneof southern Minnesota.
