I’m asking about rocks ! What do u know and what’s ur favorite
!!!!!!!!!!!!!! well. i have been obsessed with rocks since i was in. 2nd grade? my dad went abroad and brought back this massive encyclopendia of as a gift for me and well. here we are. geology and the earth sciences in general are a really fascinating field of study since we're able to infer so much about the history of a place just by analyzing the rocks and soil present there.
my favourite rocks have to be amygdaloidal basalt, pallasite, granite, and shale!
amygdaloidal basalt is a form of igneous rock formed due to basaltic lava flows. it often contains former gas bubbles, known as vesicles, where carbonates, zeolites, and agates (among other minerals) may be filled via secondary processes. the fun thing about this type of basalt are the minerals! if you're lucky, you'll find a really large individual piece trapped inside and, with a bit of skill, a hammer, and some luck, you'll be able to get the mineral out! this is a pretty common type of rock (the most common igneous rock in the world, in fact!) and you can tell a lot about the place from the minerals present inside the basalt! where i live, a lot of calcite, mica, and limestone can be found inside the vesicles, so that's cool!
pallasite is a type of extraterrestrial meteorite- olivine crystals in a shiny grey groundmass (usually an iron-nickel matrix) . i don't have any explanation for why i like these these i just think they look so cool,,,,,, plus they're from space! so shiny...!
granite is a common type of igneous rock. it's intrusive, meaning it's formed when magma cools under the surface of the earth. It's a hardy rock that forms pronounced topological features. it is composed of a matrix of feldspar, silica, and quartz. my favourite quality of granite has to be its strength and hardiness. granite is pretty resistant to erosion, which creates incredible landscapes whenever it does suffer erosion. like!!! look at her so versatile!!!
shale is a clastic sedimentary rock. it is fissile - which means it has a tendency to split into flat planes. fun fact! these are edible - my mom used to eat these as a kid, and i've tried them too. they taste..... salty, with chippery undertones. the texture is unmatchable though. crunchiest rock award winner.
ok this was my mini rant about rocks! i could go on another one about minerals all on their own but i'll save that for another time.
