Strike Slip Basin Sedimentation

• subsidence often asymmetrical resulting in rapid lateral changes in sediment thickness and facies

• on land: alluvial fans along active marginal faults, passing into fluvial and lacustrine facies towards basin centre

• volcanisum along extensional faults

• evaporites in internal drainage basins in hot, arid climates (e.g. Dead Sea rift.)
