Abstract:
Based on the mineral component and chemical composition test of rock examples from different depths in an ancient building, this paper studied the conventional method determining weathering depth according to the change of mineral component and chemical composition of rock examples in different depths. The result indicates that the change of mineral component and chemical composition of weathered rock with depth is ruleless because there is difference in the mineral component and chemical composition in different positions of this rock at the beginning of diagenesis. Thus, the conventional method determining weathering depth according to the relation of single mineral component or chemical composition with depth will became inapplicable. This paper presented a new method for determining weathering depth aiming at above condition, which determines weathering depth from the relation of chemical weathering indices with depth. Practice proves that this method presented can get accurate chemical weathering depth of ancient stone carving, grotto and rock component of building.
