identifying sedimentary rock

rock and add heat and pressure?

hint: see grains with naked eye, can see crystals with hand lens

quarts arenite

low grade metamorphism: recrystalized quartzite

intermediate: quartzite

high grade: amphibolite

rock and add heat and pressure?

hint: fragments of shell reacts to acid

coquina

low grade: calcite marble

intermediate: fully crystallized marble

high grade: marble

rock and add heat and pressure

hint: grainy has heft and powdery crystals are reaaaaallly tiny reacts to acid

chalk limestone

low grade: marble

intermediate: marble

high grade:marble

rock and add heat and pressure

hint: has gravel/big pebbles in it

conglomerate

low grade: metaconglomerate

rock add heat and pressure?

hint: super light black in color

coal

peat and graphite

rock add heat and pressure

hint: made of balls and reacts to acid

oolitic limestone

transforms into marble

rock and add heat and pressure?

hint: not really a rock, made of plant material not much heft

peat compressed plant

turns in to coal eventually graphite

rock add heat and pressure?

hint: clasts are big and angular

breccia

turns into metabreccia

what is rock and add heat and pressure?

hint big pebble clasts

congolamerate

low grade: metaconglomerate

what is the rock add heat and pressure?

hint: classy at big enough to see with the eye but just barely. grainy. color is grey

greywacke

low grade: clay and slit

intermediate: schist or phyllite

high grade:gneiss

what is this rock and and heat and pressure

hint: dry to touch and powdery. kinda looks like chalk but doesn’t react to acid. very light no float

diatomite

low grade: chert

intermediate & high grade: quartzite

what is rock add heat and pressure

hint: barely able to see the grain but has grit. light brown in color

siltstone

low grade: slate

intermediate: phyllite

high grade: schist

very high grade: gneiss

what is rock add heat and pressure

hint: reacts to acid. tiny crystals sparkle with cleavage

crystalline limestone

low grade& intermediate& high grade: marble

what is this rock add heat and pressure

hint : angular pink crystals w cleavage not gravel quartz
