按以往的观点,秋田县东北部北鹿地区的大型黑矿矿床都限制在所谓“北鹿盆地”的东、西边缘带,故以边缘部作为重点找矿区.然而,1969年盆地中部深泽矿床的发现,打破了这一定论.几乎与此同时,1965年至72年,在饵钓附近开始了黑矿探查,打了13个构造钻孔,总进尺7300米.从1974年起,根据深泽矿床积累的找矿资料及其解释获得新的找矿标志,以深泽矿床为中心,对矿床下盘的石英安山岩、其火山活动的形式及喷出时期、与黑矿矿化作用的关系等
In the past, the large-scale black ore deposits in the northern deer area in the northeast of Akita Prefecture were confined to the eastern and western margins of the so-called “northern deer basin,” so the marginal part was the key prospecting area. However, in the basin of 1969 At about the same time, the discovery of the central Shenze deposit broke the founding, and almost at the same time, from 1965 to 1972, a series of black holes were opened near the bait fishing site and 13 structural holes were drilled with a total footage of 7,300 meters. According to the mineral prospecting data accumulated in the Shenze deposit and its interpretation, a new ore prospecting symbol is obtained. Taking the Shenze deposit as the center, the quartz andesite in the footwall of the deposit, its volcanic activity form and eruption period, The role of the relationship
