There are no known porphyry copper deposits in Japan. Attempts were made in the past to explain this paradox as the Japanese islands sit above a subduction zone of the type widely accepted to give rise to porphyry‐type deposits within subvolcanic magmatic–hydrothermal systems. Is it possible that porphyry copper systems are incompatible with the volcanoplutonic setting of the Japanese islands? In other words, is the established model for the genesis of porphyry copper systems not completely correct, or is it that the elusive Japanese porphyry deposit has not yet been found? We argue that, until proven otherwise, the answer lies in the latter option.

东北北部斑岩型铜矿床的潜力(或日本2020年贱金属和贵金属矿床的勘探潜力)

日本没有已知的斑岩铜矿床。过去曾试图解释这种悖论,因为日本诸岛位于俯冲带之上,该俯冲带被广泛接受以在次火山岩浆-热液系统内形成斑岩型沉积。斑岩铜矿系统是否可能与日本列岛的火山古生物环境不兼容?换句话说,是否已建立的斑岩铜矿系统成因模型不完全正确,还是尚未发现难以捉摸的日本斑岩矿床?我们认为,除非另有说明,否则答案就在于后一种选择。
