“Iron Ion Relative Weathering Index”: A New Index for Identifying the Weathering Degree in Red Sandstone [PDF]
ACS OmegaThe red bed region in west central and southern China is affected by hot and humid climate, where sandstone is intensely weathered. The weathered hazardous rocks seriously threaten the road and slope, making it challenging to protect the Danxia red bed.
