Explanation / Answer

Slate

1.It formed from the parnet rock shale by metamorphic action.

2.Slate is fine grained and foliated type of rock.

3.It is very strong and durable duet to metamorphic condition.

4.Slate colout vary from shades of green, to red,to gray/balck, It contains minerals are qurtz and mica

Amphibolite:

1.It formed from the metamarphosim of igneous rocks such as basalt and gabro ect.

2.It composed of green, black ,brown amphibole minerals.

3.It is used in construction industry and hader than lime stone and havior than granite.

Hornfels:

1.It is forme by contact betweent mudstone or shale or other clay rich rock.

2.It is very fine grained we can observe on microscope and it shape granular and elongate crystals.

3.Generally contains minerals only formed under high temperature conditions, e.g. andalusite.

Anthracite:

1.It contains highest carbon content and highest energy density. it veries 92% to 98%.

2.It mainly use in power generation sector and metallurgical sector.

3.It has higher relative density and low valetile mater and Chemically, anthracite may be considered as a transition stage between ordinary bituminous coal and graphite.

Talc schist:

1.It is a formed by the metamorphism and deformation of ultrabasic ignous rocks.

2.Talc is softest mineral on the earth and it deeply coloured and crystallized.

3.It medium grade metamorphic rock with flat and sheelt like grains.it contains magnesium silicate.

4.This may avilable in white, gray, yellow, brown, pink, blue
