📢 🤓 Ultra-niche book alert! 🤓 Not for everybody, but this is an absolutely *stunning* book: Stearns Morse's updated 2024 edition of Basalts and Phase Diagrams: link.springer.com/book/10.1007 It is beautifully written (and often funny), comprehensive, wise and informative. This is the kind of thing you can only do using book format. If you work on igneous rocks, or in experimental petrology, read it! 🤩 🤩 🤩 #Geology #Igneous #IgneousPetrology #PhaseDiagrams #ExperimentalPetrology

SpringerLinkBasalts and Phase DiagramsThis book discusses parameters of mineral systems at high pressures, and covers essentials of physical chemistry applied to silicate liquids and crystals.

“The GEOROC Database (Geochemistry of Rocks of the Oceans and Continents) is a comprehensive collection of published analyses of igneous and metamorphic rocks and minerals. It contains major and trace element concentrations, radiogenic and nonradiogenic isotope ratios as well as analytical ages for whole rocks, glasses, minerals and inclusions. Metadata include geospatial and other sample information, analytical details and references….
Current content of GEOROC:
• 22,750 papers
• 685,660 samples
• 2,680,100 analyses
• 39,334,100 single data values…”

My two minor obsessions captured at the same moment. Here are pictures of my favourite bicycle, an old school build using a custom #DaveYates frame, resting against my favourite rock, a beautifully smooth #glacial erratic composed of a very hard, fine grained, mid grey #igneous rock with pale mm-cm sized plagioclase phenocrysts. Generations of bottoms have enhanced the glacial smoothing 🙂. Located in #MaxwellPark #Glasgow #geology #cycling

Interesting #boulders in a roughly stacked #seawall
The southern part of the spit separating #Plymouth Harbor from Plymouth Bay has a seawall along the outer shore, above Plymouth #LongBeach. Without knowing where they came from, interpreting the boulders is sketchy. BUT nice coarse crystals in intrusions into #felsic rocks, including big #quartz chunks (top right photo) and blades of #biotite (bottom right).

Plymouth bay is on the Massachusetts coast between Boston and Cape Cod. The spit protecting Plymouth Harbor (lower right) is about 4 km long.
A vein bearing large grayish quartz crystals in a fine grained ground mass intrudes into felsic rock, sunglasses for scale.
