Introduction

Investigating the properties of rocks Test 1-Apperance and texture Marble - It is made up of just one mineral, it feels and looks smooth, it is very hard and the surface looks crystallised and grainy. Slate - It's very smooth to the touch and the eye, it is strong but you can dig parts off if you squeeze your thumb nail in-between the layers, it has 1 mineral and the surface is quite flat. Limestone - It is made up of more than 1 mineral as you can see many different colours and fragments, it contains lots of sediments and fossils. The colour varies from yellow to grey and the rock is very rough. Granite - It is made up of more than 1 mineral, it fells very tough/hard, it is quite shinny, it is not very smooth and the colour varies from white to green. ...read more.

Conclusion

Rock information Granite is very strong and durable stone. It takes good polish, It is composed chiefly of quartz and feldspzr mixed with paricles of mica. The colour depends upon the predominating c onstituent of feldspar. GRANITE is popularly used as architectural stone for intereior and exterior walls, floors and monumnetal stone etc. Granite is found in Rock form and dressed in various mentioned forms:- Granite rocks are igneous rocks which were formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Granite is used for long lasting monuments and for trim and decoration on buildings. Sandstone rocks are sedimentary rocks made from small grains of the minerals quartz and feldspar. They often form in layers as seen in this picture. They are often used as building stones. Limestone rocks are sedimentary rocks that are made from the mineral calcite which came from the beds of evaporated seas and lakes and from sea animal shells. This rock is used in concrete and is an excellent building stone for humid regions. ...read more.
