When going through quartz, you will gain a white health bar, known as a quartz shield. How much of the quartz shield you have depends on the size of your digger and how much quartz you've dug from the vein. The speed of this shield decaying depends on how much your digger is growing. The quartz shield will also decay slowly, even if you're not doing any digging. This shield acts like a second ...

Gold mineralization is associated with the paleo-Pacific margin of Gondwana and is related to processes of subduction/accretion and magmatism. Northern Victoria Land (Antarctica) was part of this margin during the Paleozoic, however no occurrence of gold has been reported up to now in the Transantarctic Mountains. Here we describe for the first time gold-bearing quartz veins in northern ...
Bladed quartz is present largely in the deeper part of the vein system, beneath the high-grade gold ore zone at Hishikari. This distribution may be explained by the fact that the original bladed calcite formed at depth in the system, where boiling and loss of CO 2 initially caused the precipitation of the calcite, and quartz formed as ...

As the tectonic setting and origin of gold mineralization are di erent from typical conventional orogenic gold, some studies term these deposits "Jiaodong type" [26–28].

The main gold-quartz vein is up to 2 m wide; it has a curved geometry, strikes N-S and dips to the E. The veins architecture, typical of a composite Riedel shear structure, and the kinematic indicators suggest a reverse kinematic during the development of the veining events. Veins are extensional and shear veins; they often have ribbon/banded
