碳酸盐岩早期风化成土作用的证据

对坝陵河悬索大桥西锚碇勘探斜硐100m 深度范围内石灰岩体的风化情况进行了野外调查、斜硐编录,取粘土样进行物理性质及X— 射线衍射分析并与作者以往的研究成果对比研究,在此基础上进行了碳酸盐岩体的风化分带,建立了分带标志。研究认为岩体中所含的粘土夹层,系地下水对石灰岩溶蚀— 交代作用的产物,它代表着碳酸盐岩早期阶段风化成土情况。这一研究成果,进一步充实和完善了作者所提出的碳酸盐岩溶蚀— 交代成土理论和学说。 

EVIDENCE OF THE EARLY STAGE WEATHERING PEDOGENESIS BY CARBONATE ROCK

The weathered status of limestone in the explorative inclined shaft with 100 meters in depth at the western anchorage of the Balinghe suspension bridge were investigated.The weathered zoning of carbonate rock was carried out and the indicators for zoning was set up.The clayey interlayer of rock mass were the production of corrosion-replacement process in limestone which interacted with the groundwater.The clayey interlayer presents the early status of weathering-pedogenesis of carbonate rock.The theory of corrosion-replacement pedogenesis of carbonate rock that has been put forward by authors was enriched further.
