Petrified wood forms when mineral-bearing water percolates through buried trees, depositing quartz in fluid-filled openings in the wood or replacing the wood with quartz. This preserves the wood's structure, leaving what look like stone trees behind. The logs were replaced by silica, coloured with oxides of iron and manganese.

Dolomite may form as a hydrothermal replacement mineral and, as such, is especially abundant as a gangue mineral in the ore deposits of the Upper Mississippi Valley zinc-lead district in southwestern Wisconsin. Ferroan dolomite appears in several of the state's Precambrian iron formations. Finally, dolomite locally occurs in the state in marbles.

Sep 22, 2011· The terms "vein quartz" and "gangue quartz" are easily confused. Gangue or gang is the term for those minerals in a ore deposit that accompany the ore minerals but are of no value by themselves. Common gangue minerals are quartz, calcite and dolomite. They often occur in a layered manner that reflects the order of deposition of different minerals.
