Gabbro is an intrusive igneous rock, coarse grained, dark coloured and consists mainly of calcium rich plagioclase feldspar and clinopyroxene. Minor amount of olivine, biotite, magnetite, apatite, ilmenite and orthopyroxene can also be the constituent mineral. Gabbro is very low on silica content thus have little to no quartz content.
The rocks of the Midland Valley are mainly Old Red Sandstone which is Devonian in age and was laid down in a desert environment, together with Carboniferous age sediments such as sandstone, limestone and coal measures. There are also some Carboniferous age volcanic rocks such as the basalt lavas at Salisbury Crags and Arthur's Seat in Edinburgh.

Basalt Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances.
Basalt is commonly very fine grained, and it is nearly impossible to see individual minerals without magnification. Basalt is considered a mafic silicate rock. Among other characteristics, mafic minerals and rocks are generally dark in color and high in specific gravity. This is in large part due to the amount of iron, magnesium, and several other relatively heavy elements which "contaminate" the silica and oxygen.
Host rock is, simply, the rock surrounding the ore deposit. Host rocks, as the definition suggests, may be found as a host to any kind of ore deposit, from gold to uranium. Host rock may also be defined as the type of rock where mineralization occurs. Host rocks are significant in identifying the ...
