The research has continued according to plan during financial year 2022.New samples of volcanic rocks hosting the Kuroko ore have been collected during various short trips to the field in the Hokuroku area, around Oodate, Akita-ken. New analyses have been completed, some at Akita University, and others have been made in external laboratories.These analyses included chemical analyses of volcanic rocks, collected from the field, and ore samples, deriving from the collection of Akita University. Chemical analyses allow to understand the abundance of metals (including Zn, Pb, Cu and others) in the analysed samples. Mineral analyses of the main minerals have been completed with th instruments available at Akita University. In addition, mineral identification analyses have been completed as part of student projects. A compilation of the results available so far is currently being made. The new results will be be compared with previously published analyses.A paper on the geology of the Kuroko ore of the Hokuroku area, which reports the results of the study in the last few years, has been published recently in a international journal, as detailed below.Agangi, Manalo, Takahashi, Veeravinantanakul, Elburg, 2022.

在2022财政年度，研究工作按计划继续进行。在秋田县大馆市周围的北六地区，通过多次短途考察，收集了新的火山岩样品。在秋田大学和外部实验室进行了新的分析，包括对从现场收集的火山岩和从秋田大学收集的矿石样品进行化学分析。化学分析可以了解分析样品中金属（包括Zn，Pb，Cu等）的丰度。利用秋田大学现有的仪器完成了主要矿物的矿物分析。此外，矿物鉴定分析已完成作为学生项目的一部分。目前正在汇编迄今为止获得的结果。新的结果将与以前发表的分析进行比较。最近在一份国际期刊上发表了一篇关于北陆地区黑子矿地质的论文，其中报告了过去几年的研究结果，详见下文。Agangi，Manalo，Takahashi，Veeravinantanakul，埃尔堡，2022。对矿物学和岩石学的贡献177，115。
