Lab 1 Rocks & Minerals

LAB 1: IDENTIFY ROCKS AND MINERALS Name: _________Ben Welling______ Section Time:__Mondays @ 2:00 __________ [40 pts, 4 pts each] Sample Number Color Grain Size Hardness Streak Color Other Comments Mineral or rock name 1 White Grainless 7 Transparent/White It has a large crystal, Quartz 2 Tan/ Earth Grey Coarse 4 Has large course sediments, Very dense, rough texture Quartzite 3 Grey/Black Very small Smooth 6 Black Very smooth, flat rock Basalt 4 Grey Very Fine and smooth 3 Light to dark brown Smooth very fine, not heavy for its density Slate 5 Tan Fine but with a few coarse sediment s 4 White streak Has layers in the rock, looks cemented together Reacted to acid with fizz Limestone 6 White/ and black Smooth, small grain size 3 White Difference in color, two different distinct colors, Reacted to acid Marble 7 Brownish/Red Smooth, no grains 7 Brown Smooth and fine Chert

8 White, with black and grey spots Grain size is coarse with few sediment s 6 White Very smooth ends with coarse sediments in it Granite 9 Grey Coarse but no large sediment s 6 White Feels light to the density, very rough Pumice 10 Earth colored, brown Very smooth 7 White Feels heavy, looks like it is made of sand. Sandstone

LAB 2: Campus Rock Hunt 40 pts, 8 pts each Name: Ben Welling Section Time: _Mondays 2:00, Lecture T,Th- 11-12:30 Our class has found itself stranded on an unfamiliar island!!! Where are we? How did we get here? What is this land, and how did it form? To survive and interpret information about our new surroundings, we will attempt to categorize the wild and unknown rock species scattered throughout this land (UARK campus but not Gearhart.) We will collect as much information as we can, and then take that information back home (turned in to the lab instructor) after we are rescued. Directions: • Working in groups of up to three (3), record information in a notebook, on paper, or in this document about the rocks you find on your journey. • Your team will need to systematically identify five (5) rocks and/or minerals in the field. • The following information needs to be recorded: 1. The rock or mineral’s location on campus (e.g., building name or GPS coordinates) 2. Grain size (course, fine, or glassy) 3. Color 4. In situ (placed there by nature), or moved there by humans 5. Extra notes and unique observations 6. A photo or sketch of the rock 7. Rock or mineral? If it is a rock, what type? 8. Hypothesized name for each rock/mineral (what you think the rock/mineral is). A hypothesis is not a guess, it is based on the research that you have performed and could be tested further. • Turn your results into the instructor by submitting the assignment on Blackboard. Sample 1  The rock or mineral’s location on campus (e.g., building name or GPS coordinates) 36.261163, -94.170310  Grain size (course, fine, or glassy) Coarse with medium grain size of rocks  Color – White/Grey

 In situ (placed there by nature), or moved there by humans? Moved my Humans  Extra notes and unique observations Looks shiny in some spots, very hard for density  Photo or sketch of the sample   Rock or mineral? Rock type? Rock - Quartz  Hypothesized name for rock/mineral Quartzite Sample 2  The rock or mineral’s location on campus (e.g., building name or GPS coordinates)  36.261163, -94.170310  Grain size (course, fine, or glassy) Very Coarse small rock fragments throughout  Color Brown  In situ (placed there by nature), or moved there by humans? Moved there by Humans  Extra notes and unique observations Small fragments throughout rock, Rigid texture,  Photo or sketch of the sample

Chert Sample 4  The rock or mineral’s location on campus (e.g., building name or GPS coordinates)  36.261163, -94.170310  Grain size (course, fine, or glassy) Fine, small rock fragments  Color White  In situ (placed there by nature), or moved there by humans? But there by Humans  Extra notes and unique observations It is light in density, different colors, with small coarse fragments  Photo or sketch of the sample   Rock or mineral? Rock type? Rock  Hypothesized name for rock/mineral  Limestone Sample 5  The rock or mineral’s location on campus (e.g., building name or GPS coordinates)  36.261163, -94.170310  Grain size (course, fine, or glassy) Smooth, Fine  Color Brown  In situ (placed there by nature), or moved there by humans? But there by Humans

 Extra notes and unique observations Smooth, Can rub off streak with finger, Not Hard  Photo or sketch of the sample   Rock or mineral? Rock type? Rock  Hypothesized name for rock/mineral  Sandstone
