Lawas Sandstone (1)

At the Lawas town near the market, this slightly orangey brown fractured sandstone core was extracted from about 12m below ground level. 
The light orange-brown colour is due to the stain apparently from reddish brown clayey silt deposited at the joints, probably due to water percolation.

Lawas is at the northern region of Sarawak, close to Sabah. It lies on a younger geological formation compared to the Western or Central Sarawak.
