minor fold मीनिंग इन हिंदी

Mudstones, siltstones and sandstones which had been deposited in deep water on the northern margin of an ancient continent ( Avalonia ) in the early Ordovician Period were chaotically disrupted by a huge undersea avalanche to form an olistostrome deposit in which blocks of rock are now embedded in a matrix of mudstone, and intensely deformed by minor folds, slumps and shears.
