Senor Doug >> "Llanoite" is granite from a particular part of Texas prized for its colors – it includes blue topaz and a rather pink microcline (I think that is the pink mineral).<< Wow ! Where in Texas? >>Some granites may have multiple colors of quartz, but that is likely more the exception than the rule. I expect colorless quartz most of the time from granites. << I agree… colorless quartz makes up a remarkable percentage of all the materials I have looked at closely. Not a whole lot but constantly working on it. Even the darkest granites I looked at break up into mostly clear particles. The deep tints are thin sheets of colors (mica?) &or feldspar between the quartz crystals and when the crystals pop apart the sheet looks like it shatters. I never expected mostly clear quartz until I looked myself. Like you mentioned the giant granite batholiths that have a consist combination of elements. This huge wide area of consistent demonstrates a layering or stratified condition of the materials in the earth. The core of solid metals another layer. The presence of other combinations of metals in close proximity leads me to conclude they may be separated into single or multiple layered groups. As the cracks opened up to different depths and certain amounts of material from sets of groups pours into the crack and get mixed up together then as the cracks close back up the mixed group is injected into cracks and seams where we find them. This is the process where so many different types of mixtures can be found in isolated and repeated groups. Kamron
