黑龙江省地域辽阔,由于地处边陲,交通困难,覆土掩盖,虽经二十多年来广大地质人员共同努力,地质调查和地质研究程度仍然较差,至今一比二十万区域地质调查工作尚未完成。而一比五万区域地质调查以往仅在矿产普查范围内开展了一些面积不大的非正规的地质草测,没有一幅正规出版的区调报告和图件。
Due to the vast territory of Heilongjiang Province, due to its location in the border area, traffic difficulties and overburden cover, geological survey and geological research are still underway despite more than 20 years of joint efforts by geological experts. Up to now, more than 200,000 regional geological surveys have not yet been completed carry out. In the past, more than 50,000 regional geological surveys carried out some informal geological surveys of a small area within the scope of the mineral census. There was not a formally published quarterly report and maps.
