Rock Hunting Adventure: Seek Igneous, Metamorphic, and Sedimentary Rocks!

Embark on an exciting rock hunting adventure! We are on the lookout for three types of rocks: Igneous (Basalt), Metamorphic (Marble), and Sedimentary (Shale). Basalt, which can be found near volcanoes, is fine-grained and varies from grey to black. Marble, light-colored and unfoliated, is formed under heat and pressure, while shale is a fine-grained, layer-splitting rock that is mostly gray. Rewards include a trip to the volcano, hiking boots, and a science rock kit. Join the search for these fascinating geological treasures!

  1. Wanted Igneous Rock-Basalt You will find this rock near volcanos.It is fine-grained, and could be any color between grey to black. This rock also may have certain parts of it that have much larger crystals then another part. To help you find this rock you should know the composition of it. It’s made of mafic, amphibole and pyroxene, sometimes plagioclase, feldspathoids, andquartz sometimes olivine. Reward-Trip to Volcano

  2. WANTED Metamorphic Rock-Marble This rock can be found anywhere where heat and pressure can be applied. This would be pretty much anywhere on the ground. Marble is light colored, and is unfoliated. That means that the mineral grains are random with no pattern to them. This rock is composed of either calcite or dolomite. Reward- Hiking Boots

  3. WANTED • Sedimentary Rock-Shale • 70% of the rocks in the world are Sedimentary, so it won’t be to that hard to find Shale. It is fine-grained, and splits into many layers where it is weaker. It is mostly always gray. This rock is made of clay minerals and quartz. • Reward- Science Rock Kit
