This order was from most <br />to least common listing color, rock type and texture (i.e. most to least obvious). So the <br />listing is in order of amount and order general obviousness. <br />Percentage of sample <br />Color <br />Rock Type (maybe some modifiers) <br />Texture (such as grain size, etc.) <br />Since some of the samples were both dry and wet, all samples were wetted prior to being <br />described. <br />To describe a sample <br />1. A representative group from the bag is placed into a strainer <br />2. The level of the sample is mentally noted. <br />3. The sample is washed and the change is volume is noted. This is an <br />indicatiat of washed away clay. <br />4. The sample is poured into a tray and examined tinder a light and <br />magnification. <br />5. Using the info from step 3, and a percentage estimation chart, the <br />percentages are estimated. <br />6. Color, Rock Type, and maybe Texture are noted. <br />7. Sizes are made right off a grain card. <br />8. Other notes may be made (specific sizes, roundness, and sphericity). <br />• <br />x wro.[ c,ov,ns [s r..ua,y tG <br />COLOG <br />"^+~°x or urv[ ausnxs<x ~~ F <br />
