植物能对它所处的地质环境作出反应,因为,在矿体风化土壤中某些富集矿物的元素含量相对较高,使某些植物生态发生异常,有的矿物元素可促使某些植物生长,使其更加茂盛;而有的矿物元素则能使某些植物中毒,枯萎或畸形;还有些植物因吸收了某种矿物元素而失去本来面目,发生变态等等,我们可以把植物的这种生态异常现象作为一种找矿标志,寻找隐伏矿体。例如,海州香薷,俗称铜草,它是寻找铜矿的有效植物标志,有铜草生长的地带可指示下部有铜矿存在。我国长江中下游诸省及山东、陕南等铜矿区均普遍发现有这种植物。生长在铀矿床区土壤中的紫云英花瓣呈现谈红色,因此,紫云英是找铀的重要标志;生长在锌矿区风化土壤中的车前草,因吸收大量的锌元素,花的颜色格外鲜艳夺目,以此作为找锌的标志,硼元素大量富集的土壤中生长的猪毛菜枝叶会因中毒出现畸形而扭曲,这一现象 Plants respond to the geologic environment in which they live because of the relatively high levels of some mineral-rich elements in the weathered soils of the ore body that some of the plants are ecologically abnormal and some of which promote the growth of certain plants , And make it more lush; and some mineral elements can make some plants poisoning, wilt or deformity; some plants due to the absorption of a mineral element and lose its true colors, metamorphosis, etc., we can plant this Ecological anomalies as a sign of prospecting, looking for hidden ore body. For example, Haizhou fragrant mullet, commonly known as copper grass, is an effective plant symbol for the search for copper mines, and the zone of copper grass growth indicates the presence of copper deposits in the lower part. The plants in the middle and lower reaches of the Yangtze River in China and in copper mines in Shandong and southern Shaanxi are generally found. Therefore, aspartame is an important symbol of uranium found in the soils of uranium deposits. Plantain growing in the weathered soils of zinc mines, due to the absorption of large amounts of zinc, Particularly bright eye-catching, as a sign of looking for zinc, a large number of boron enrichment of soil growth in the hair of the branch of the pigweed will be distorted due to poisoning deformity, this phenomenon
