正确答案

①确定预测要求:确定预测的目的任务、预测区范围、预测的资源种类、具体的比例尺。
②全面收集地质资料:全面搜集研究地区的各种地质报告和图件、物化探、重砂测量等工作成果及有关专著,并尽可能进行矿产预测所必须的底层、构造、岩浆岩、矿床等各项地质资料的系统整理,使之条理化和图表化,为进一步研究成矿规律和预测打下基础。
③研究成矿规律和建立矿床成矿模式:在深入研究区域地质背景的基础上,通过一系列点型矿床的控矿因素和成矿机制及对区域控矿条件的分析,找出在时、空和物质来源方面直接控制矿床形成和分布的规律。
④编制预测图:通常以成矿规律图为底图,要突出各种控矿地质因素和矿化信息。
⑤重点工程的验证:对复杂地质体的评价预测,必须要有实践—认识—再实践—再认识的不断深化过程。
⑥编写报告:成矿预测报告应根据不同比例尺预测的主要任务,以能说明情况、问题和预测成果为原则进行编写。内容一般应包括概况、工作和研究程度、地质背景、成矿规律与成矿预测、对地质工作部署建议等部分。
