摘要
根据红土型镍矿的地理分布和成矿特点，提出红土型镍矿的勘查技术规范和方法以及投资红土型镍矿项目的研判方法。结果表明，红土型镍矿的成矿和分布主要受基岩的蛇纹石化强度、气候因素、断裂发育情况、地形地貌和大地构造环境所控制。对于红土型镍矿项目，一般抽取原工程量的5％～10％进行重采样或钻探验证，核实资料可靠程度和资源量。验证工程布设应遵循系统性原则、均匀性原则、突出性原则和互印证原则。红土型镍矿地质勘查分4个层次：战略靶区筛选（项目建设，约1000km2），找矿前景评价（预查，约100km2），概略性经济评价（普查，约10km2）和经济性评价（详查或勘探，约1km2）。
This paper, according to the distribution and mineralization of laterite nickel deposits, presents technical guideline, exploration method and project assessment in investment. Their mineralization and distribution is jointly controlled by serpentinization extent, climate, faults, terrain and tectonics. To verify the laterite nickel exploration, 5% - 10% of the original projects need redoing or re-drilling in accordance with systematic, equal, protruding and inter-testifying principles. Geological exploration can be divided into four levels, targets generation （project construction, 1 000 km2）, potential assessment （ ce, 100 km2） , pre-feasibility study （survey, 10 km2）, and feasibility study （detailed exploration, 1 km2）.
