kingwinner Posted November 13, 2005 Report Share Posted November 13, 2005 I will have a practical mineral test next week -- a pain! Please consider the appearance and luster of each mienral only because I can't perform any hardness, streak test in the practical test next week! Just by "looking" at it! Please click the following address for the image of the minerals!http://www.geocities.com/asdfasdf23135/DSC00586.JPG1) The numbers 2-gypsum, 4-fluorite, 7-quartz, 14-glass look so alike to me, is there any difference in appearance in these four things that can allow us to distinguish from one another? 2) The numbers 3-calcite, 6-orthoclase feldspar, 15-alabaster look exactly the same to me, is there any difference in appearance in these three things that can allow us to distinguish from one another? Please click the following image for the second set of minerals!http://www.geocities.com/asdfasdf23135/DSC00595.JPG3) Number 15 is called a "quartz crystal", how is it different from a "quartz mineral"? Who has good mineral-identifying skills? I find it hard to differentiate one mineral from another! I really really need your help! Thank you! :hihi: Quote Link to comment Share on other sites More sharing options...
