Jiaojia-type gold deposit that discovered by Shandong geologists in the northwest Jiaodong Peninsula in the 1960s is a new type of gold deposit. It has gone through twelve years of exploration and scientific research from discovery to establishment. The new type of gold deposit has been rapidly promoted after its establishment, and has achieved fruitful prospecting results in China. The deep exploration achievements of Jiaojia-type gold deposit constantly spring up in Jiaodong area since the 21st century. The accumulated gold resource reserves submitted have been 3, 617.12 tons by 2020, which has helped Jiaodong area become the third largest gold cluster in the world, and China's gold reserves have risen to the second place in the world. While continuous breakthroughs have been made in the deep exploration of Jiaojia-type gold deposits, great progress has also been made in the scientific research. For example, the metallogenic age of gold deposits has been precisely defined, major breakthroughs have been made in the research of metallogenic dynamics background, the understanding of the source and evolution of ore-forming materials has been more in-depth and refined, and the metallogenic model has been more perfect. The research of metallogenic depth and prediction also shows that the Jiaojia-type gold deposit has great potential for deep prospecting. These research works enriched the metallogenic theory of Jiaojia-type gold deposit, make the metallogenic prediction results more accurate and reliable, and effectively guide the gold exploration in the Jiaodong Peninsula.
