拉美地区钾盐资源的分布及成矿规律分析

全球钾盐资源储量丰富但分布极不均衡，绝大部分钾盐资源集中在加拿大、俄罗斯等国。拉美地区已发现钾盐资源，多数为含钾卤水，少部分为地下固体钾盐，发现拥有钾盐资源的国家有巴西、阿根廷、玻利维亚、智利和秘鲁等国。通过对拉美地区钾盐资源分布及开发利用现状进行分析，总结了中国企业开展境外钾盐开发合作中的困境，并对拉美各国开展钾盐矿产资源勘查开发的可进入性及优先进入目的国进行了评价与讨论，这为中国地勘单位和企业到拉美进行钾盐勘查、开发投资提供科学指导。

Distribution and metallogenic regularity of potash resources in Latin America

Global potash reserves are rich，but the distribution is very uneven，most of the potash resources are concentrated in Canada，Russia，and other countries.Latin America has been found that the majority of potash resources are potassium brine，and a small part of them are the solid potassium salt.The countries，such as Brazil，Argentina，Bolivia，Chile，and Peru are all found with potash resources.Based on the analysis on the distribution and development and utilization status of potash resources in Latin America，the plight of China′s enterprises in the cooperative development of offshore potash mineral resources was summed up，and the accessibility and preferentially accessible Latin American countries to carry out survey and exploration of potash mineral resources were evaluated and discussed，which provided scientific guidance for Chinese geological exploration units and enterprises to make exploration，development，and investment in Latin America.
