A heart made of feldspar minerals in a granite
Simbalito presenting the heart shaped minerals
Today: during #hedgewatch on #Fuerteventura we found this #granite that was greeting us with a #heart made of #feldspar - interior & rim are feldspar. The other #mineral's are #quartz & #mica.
We wish a wonderful Sunday

Yesterday's #hedgewatch included a sand #beach. In the video you see #sand transported by the #wind . Some particles roll & some jump. The latter mechanism is called saltation in #geology Its also pawt of #dune formation in the #desert

Simbalito is visiting a saline on Fuerteventura
Today we visited during #hedgewatch a #saline 😻 A place where humans use the #sun to evaporate #seawater & to harvest #salt or in more detail #tablesalt #NaCl. Many other types of salts exist so you need to be careful to harvest the correct one

The humans are on #hedgewatch and look for the #rocks at the airport. It's a #granite with the 3 suspects #mica (black), light grey #feldspar & dark grey #quartz

Simbalito showing glacial striations
Simbalito is presenting glacial striations with the striations marked
Today: during #hedgewatch in the #Alps near the #Aletsch #glacier we found these glacial #striations. The scratches are probably from the #LittleIceAge .The glacier was much thicker. They are cut in by #rocks at the bottom of the glacier.

Simbalito is presenting a fold
Simbalito is presenting a fold with the fold labeled in this picture
Today: during #hedgewatch in #Switzerland we found this deformed #rock. It underwent #ductil #deformation so that this #fold made of #quartz formed. During deformation material can move from the limbs to the hinge so that the hinge becomes thicker.

Simbalito is presenting a quartz vein in granite
Today #GeologyWithCats. We found during #hedgewatch many #quartz veins at the #Rosstrape. They formed when #silica rich fluids circulated in #fractures that formed during cooling of the Ramberg #pluton & are now remnants of a #geothermal system.

Drill core from a sedimentary rock showing fluid escape structures
Today #GeologyWithCats! We found this #drillcore it's a #sandstone. The white layers had large pores with #water in it. When #sediment was accumulated the pressure was growing & finally the water was squeezed out upwards-its a water escape structure.

Simbalito is sitting on a piece of lava that contains bubble's
Today is #VolcanoThursday 😻 During #hedgewatch on #Tenerife I found this #lava piece with bubbles. #Magma contains gas & when it travels to the surface it cools down & pressure drops so the gas is released & makes bubbles.

Today 2a ago my humans met this little #toad during #hedgewatch & found also this piece of #limestone with #fossils. The fossils are stems from #crinoids i.e. small animals also called #sealilies. We love this name

Quartz crystals as only remnants of the rock matrix
Today #geology from my #hedgewatch on the #Seychelles. There most #rocks belong to the #granite's & exist of #quartz, #feldspar (FSP), & #mica. Granites aren't happy in warm & humid #climate's because the FSP weathers very fast away while the quartz stays longer.

Volcanic rock with spherical lapilli
Volcanic rock with spherical lapilli
Today is #VolcanoThursday. These are #lapilli in #buildingstone. Lapilli describes the size of #tephra-a #volcanic #rock. These are accretionary lapilli-round particles formed in a wet cloud of volcanic ash. Found during #hedgewatch on the #Azores

Today is day 16 of #30DaysWild. During #hedgewatch my humans found #flintstone/#flint/#Feuerstein😻 Pawesome🐾 Flint is made of #quartz & forms often in #chalk. The silica is probably from the skeleton of #sponges. The exact formation isn't clear yet

Today is #FossilFriday & I taught my humans that to be a #fossil the specimen needs to be at least 10.000 a old. That doesn't hold for this #corals, but this is basically how fossils of corals look like. We found them during #hedgewatch on the #Seychelles.

Today 3D #PillowLava for #VolcanoThursday. Such #lava forms during underwater #eruption's & is often #basaltic. Cold #water causes formation of a skin. Following lava inflates the body until the skin ruptures & forms new pillow's.
