广东省亚髻山地质遗迹特征及成因分析

The Analysis of Characteristics and Genesis of Yajishan Geological Heritage, Guangdong Province

亚髻山地质遗迹点位于广州市从化区良口镇石岭村和佛冈县四九芒寨村一带,球状风化体主要分布在山腰和山顶坡度转折较大的地方,最大的球形风化体直径可达4-5m;球状风化体的形成主要受控于自身岩性特征、所处构造环境以及当地气候条件,物理化学、生物风化等作用沿岩石节理方向渗透,使得岩体顶部最先遭受侵蚀,经过地质作用的改造进而形成形态各异的"石蛋";亚髻山地质遗迹点的球状风化"石蛋"具有很强的科学与美学价值,是珍贵的地质遗产,建议加以宣传并保护,建立地质公园对其合理开发利用,将地质资源与旅游规划结合起来,为当地创收提供新思路。

The Yajishan geological heritage is located around Shiling Village, Guangzhou, and Sijiumang Village, Fogang, where the spherical weathered bodies are mainly distributed in the places of the slope of the mountainside and the top of the mountain. The largest spherical weathered body diameter up to 4-5 m. The formation of spherical weathering bodies was mainly controlled by lithological characteristics, the tectonic environment and the local climate conditions. The top of the rock was eroded firstly along the direction of rock joints by the effect of physical chemistry and bioweathering. Geological transformation make the rock into different shapes of ＂stone egg＂, a precious geological heritage with scientific and aesthetic value, proposed to promote and protect, and geo-park should be established under rational development and utilization, which is a combination of geological resources and tourism planning, to provide new ideas for local income.
