True. Quartz is a mineral, and can be deposited in any number of ways. In this case, based on gross physical appearance, I'd say the shiva lingams are likely made of a type of jasper, but I'm not qualified to tell. Given the fact that they're definitely more coarse-grained than other varieties like chalcedony and agate, I'm not even sure 'cryptocrystalline is the correct way to describe them - perhaps someone else who has a background in geology/mineralogy and is familiar with shiva lingams can comment here. The layering that can be seen in them is reminiscent of banded claystones; that's why I said sedimentary, but I could well be wrong. Jason
