Gupushan-Type Marble Stone Forest Landscape in Hezhou, Guangxi
Reference work entry
This is a representative type of carbonaceous stone forest landscape composed of Devonian limestone. The Gupushan marble stone forest in Hezhou is a typical example. This landform developed along the contact between Middle and Upper Devonian carbonate strata and granite. It is a skarn-type tin sulphide deposit. The development of vertical joints caused the formation of a large area of dense corrosion trenches, stone pillars and dolines. An iron cap and a weathered laterite layer are interbedded in the strata, forming a layer of secondary placer tin ore that has been mined since the Song Dynasty. As a result of the excavations, vertical and horizontal marble pillars have been exposed. The columns are 10–20 m high, and the highest reaches 30 m. The columns are mainly in conical, columnar, or form sharp peaks. The column surfaces are smooth and rarely have traces of rainwater erosion, but with the characteristics of subsurface karst corrosion. This stone forest is thought to have formed...
