There are stylolite and the “tiger stripe” structure on the longitudinal section of the limestone. The stylolite is the zigzag-like irregular line (plane) formed in the unconsolidated sediment by the gravitational difference as a result of pressure solution in the deuterogenic stage of rock. Otherwise, the “tiger stripe” is the dolomitic limestone caused by the dolomitization, which looks like the “tiger stripe” or the “leopard spot” projecting on the rock surface because of its more intense weathering resistivity.
