|Here they are all labelled up.|
Because I think rocks are more interesting the closer you look, here are some macro shots taken with my field lens and smartphone camera!
|Gabbro - a coarse-grained intrusive igneous rock, formed when magma slowly solidifies deep within the Earth's crust. Consists mainly of pyroxene, plagioclase feldspar and olivine.|
|Serpentinite - a very variable metamorphic rock, formed from peridotite which originates from the Earth's mantle; it has been uplifted to the surface and in the process been extensively altered.|
|More serpentinite - showing how variable it is!|
|Quartzite - a sedimentary rock (sandstone) consisting of well-cemented quartz grains. This rock looks dull and boring from a distance, but close to the quartz grains sparkle!|
|Limestone - a sedimentary rock formed in an ancient coral reef, mainly from fragments of calcite shells and skeletons of reef-dwelling animals - here you can see some crinoid stem plates.|
|This quartz has precipitated into a fissure in the limestone. Lovely stuff!|
