Langcliffe parish lies between two ancient fault lines: theMiddle Craven and North Craven Faults. The rocks in this area aremainly Great Scar Limestone and some of the Yoredale Series, whichboth belong to the Lower Carboniferous period. There is also a narrowband of Silurian rocks that extends from just south of Malham Tarn to theRibble valley. The carboniferous limestones provide the main buildingmaterial in the village.The geological history of the parish begins in the Silurian period around420 million years ago. Sedimentary rocks, which comprise sandstonesand siltstones of the Austwick Formation, were once eroded materialtransported by rivers into the sea, where they were deposited. At the endof this period, two continental plates collided and alternating layers ofsandstone and siltstone were crumpled into a tightly folded landscape,and later partly worn down by river action.13
