东秦岭泥盆系沉积岩相地质遗迹及保护意义

THE DEVONIAN SEDIMENTARY ICHNOFACIES IN EASTERN QINLING AND ITS PROTECTION SIGNIFICANCE

建立于秦岭腹地柞水、镇安两县交界的泥盆系沉积岩相地质剖面，有陆相冲积相、过渡相河口湾相、海潮坪相、陆棚相、局限台地相、开阔台地相、台缘生物礁相、台缘斜坡相及次深海盆地浊积岩相，整体反映一微型镶边碳酸盐台地的形成与消亡，保护该地质遗迹对地质科学研究具有重要的实际意义。该剖面已被批准为陕西省第2号自然保护点，并已立碑保护。

The geological profile of the Devonian sedimoptary facies, which was established in the boundary between Zhashui and Zhen’ an counties in Qinling, contains continental alluvial facies, transitional facies, estuarine facies, marine facies, lakeshore facies,shelf facits, limited platform facied, open platform facies, marginal biohermal facies, marginal clinothem facies and sub -deep-sea basin turbidite facies. They all reflected the formation and deterioration of a microrimmed carbonaffe platform. Protection of the geological relics is significant for researches. This profile has been appointed as a second-class natural protection spot and some special steles have been set up for the protection.
