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.

Today is another special day
2 a ago during #hedgewatch on #LaGomera's highest point during #sunset the "thing with the ring" happened
The #gemstone on the #EngagmentRing is a #sapphire a variety of the #mineral #corundum which is aluminium oxide #Al2O3
Today is a very special day 
5 a ago Simba
moved in & our adventure started. It took him very long to feel home even though Ornella helped a lot. Simba became #hedgewatch'er & was a pawsome family member 
We miss him
Today is #VolcanoThursday. Lately #earthquake swarms occurred on #Tenerife. Upflift since 2023 is 1 cm. That’s supawfast in #geology! The #volcano #PicoViejo on Teides W-shoulder erupted in 1798. Last #eruption was #ElChinyero in 1909. Paws crossed for NO bad news
#GeologyWithCats
Today 5 a ago our humans met Simba for the first time It took time & a lot #friendship tuna to make him feel home. Simba became a fantastic furiend, great #hedgewatch'er & self-confident #cat The humans are grateful for the pawsome time

Today I have impawtent news I got company These 2 moved in today. They are both rescues & about 8 months old. Both got new names. The tabby is Jasper & the tuxedo is Mica. I will teach them how to #hedgewatch & how to post #GeologyWithCats
Simbalito

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 is the 1st #VolcanoThursday of 2025. This is the #Orotava #valley on #Tenerife formed by a gigantic #landslide. The island was growing so fast that its flanks became unstable & collapsed. At least 500 km3 #rock's moved down causing a #tsunami
Dear friends it was quiet on this account, because Simba got his wings one month ago on the 19th November. It was a short fight against pancreatic cancer. We are still sad... Simbalito will take over the account. Simba will never be forgotten & stays forever in our hearts
Until we meet again 
This #VolcanoThursday is the 61th birthday of Surtsey a #volcanic island 30km S of #Iceland. It's named after Surtr a fire giant in northern mythology. The eruption ended June 1967. Only scientists are allowed to #hedgewatch there
Today at #MinCup24. We are in the semifinals & my favourit is the #DoesItCat #mineral #kyanite/#disthene-the mineral of 2 hardnesses-or in cat-of the 2 softnesses. II the c-axis {001} it has a 5 & perpendicular to it a 7 on the #MohsScale.
Go #TeamKyanite
Today I found a Glückssteindepot-a lucky rock depot-during my #hedgewatch close to the #AletschGlacier/#AletschGletscher. A place where you can deposit small rocks and in return you get lucky. I have put some #rocks in for my friends
Today #calcite is on of the competitors in #Mincup24. That's all I need to know: in memory of Ornella I'm in #TeamCalcite, or team #sunstone because of the very high #birefringence of #mineral calcite. First picture is from Ornellas first MineralCup
#mineral #GeologyWithCats
Today: dear #Mincup24 team. I sent you greetings from #Switzerland. Look whom I have met today during my #hedgewatch. A very young #IceMin, it formed last night, is greeting you It hopes also to become again part of the #MineralCup in the future

Today is the first duel of #MinCup2024. It's the well known #kaolinite, an important ingredient for #porcelain/#china, vs. the rare #mineral #abelsonite. Doesn't matter how rare... #foodbowl beats everything 
#DoesItCat ? Of course
Today is #NationalBeachDay we love beaches because they are great #hedgewatch locations & pawsome places to train awareness They can be very different Black beaches are indicators for #volcanic #rocks as source of the #sand. Thanks Hedgewatchers for keeping us updated
Today we are again on #Lanzarote for #VolcanoThursday. This place is called #CiudadEstratificada-#StratifiedCity. Its a bizzare #landscape purrfect for #hedgewatch & made of layers of #volcanic ash. The layers #weathering resistance is varying - thus the shapes.

Yesterday was #VolcanoThursday & the picture is again from the #volcanic island #Lanzarote. Can you see the semicircles made of #rocks? Each hosts a #grapevine. Here a layer of volcanic ash collects can store humidity& protects the plants from the wind.
Prost Cheers
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
