Little (< 0.3 mm) intercumulus crystals of dalyite (bright interference colours) surrounded by alkali feldspar in a peralkaline syenite. #thinsectionthursday #geology #science #minerals #rocks #microscope #microscopy

An photomicroscopic image of rock (syenite). Taken in cross-polarised light, small crystals of dalyite show bright interference colours. Surrounding alkali feldspars appear first order grey.

Spectacular olivine dolerite from Fair Head, County Antrim in XPL for #ThinSectionThursday. Olivine shows particularly vibrant interference colours while the ophitic intergrowth of twinned plagioclase and clinopyroxene is a textbook quality example. 🧪⚒️🌋

Photomicrograph of olivine dolerite. Isolated, euhedral to subhedral olivine phenocrysts (showing second and third order interference colours) are surrounded by a groundmass made up of opaque iron oxides and an ophitic intergrowth of small, euhedral plagioclase laths surrounded by large clinopyroxene crystals.

Olivine and clinopyroxene phenocrysts in a plagioclase-rich groundmass - Vesicular basalt lava flow, Azores #thinsectionthursday #geology #science #minerals #rocks #microscope #microscopy

An image of a rock thin section viewed under the microscope in cross polarised light. The sample is dominated by large olivine and clinopyroxene crystals which are exhibiting bright second order interference colours. They are set in a much finer groundmass which contains abundant plagioclase crystals, recognisable through their first order grey interference colours and long, thin crystal shapes. Large vesicles are scattered through the sample, appearing rounded and black.

While I'm advocating for plane-polarised light, here is some nice hauyne (blue), alongside leucite (colourless, varying size), and a small amount of clinopyroxene (greens/browns). #thinsectionthursday #geology #science #minerals #rocks #microscope #microscopy

An image of a rock thin section viewed under the microscope. Prominent blue crystals of the mineral hauyne stand out from the background of white leucite.

An image of a rock in thin section, displaying crystals of various minerals (kyanite, sillimanite, muscovite, chlorite, plagioclase). A schistose texture is observed, with the muscovite being aligned and appearing to 'flow' from top right to bottom left of the image.

A serpentinite mesh texture for #ThinsectionThursday. Or is it a piece of modern art? 🖌️ Note how there are several generations of serpentine, among them a clear one that filled the first fractures, and a dark one (full of magnetite) that replaced the rest of the olivine.

The isle of Rùm and its layered intrusion remain undefeated for thin sections. Foliated troctolite (ol+plag) or 'allivalite' from Hallival, in the NMS rock collection. #ThinSectionThursday

Just one of the best thin section images you're likely to see. Brightly coloured fresh olivines in blues, yellows, and oranges among smaller black, white and grey plagioclases, which generally define a fabric from left to right.

Glassy lava from Tongoa Island, Vaunatu, in plane polarised light. Clinopyroxene and plagioclase form glomerophyric clusters. These are surrounded by rounded vesicles (gas bubbles) frozen into the brown glass (liquid) when the lava was rapidly quenched #ThinSectionThursday 🧪⚒️

Tried a diff. approach w/ PPT slides this year. Rather than slide numbers, the slides transition from morning through to evening to indicate progression, with diff. animals throughout. Gives the chance to sneak one easter egg into each lecture too. #highereducation #teachers #edusky #education

A local #ThinSectionThursday today. Clinopyroxene- and olivine-phyric basalt from Holyrood Park, Edinburgh. Location given as St Anthony's Chapel, so probably lava two or three of the Arthur's Seat lava succession.

A photomicrograph of a basalt between crossed polars. It is full of large colourful clinopyroxenes, some round grey vesicles, and some yellowy grey altered olivines. The groundmass is full of little plagioclase feldspars and iron oxides.

A nineteenth century Krantz thin section of 'forellenstein' (literally "trout-stone"), an old German name for troctolite – an ultramafic olivine+plagioclase rock. From the NMS thin section collection. #ThinSectionThursday

A photograph of an old glass microscope slide on a white background. The pale round rock section is covered by a glass coverslip with yellow resin round the edges. A green handwritten label at the top says "No. 69 Forellenstein Volpersdorf, Schlesien". A tan coloured label at the bottom says "Krantz 1893, 24, 369".

The rock slide from the previous image zoomed in slightly and between crossed polars. It shows black, grey, and pale yellow striped plagioclase and purple and orange olivine.

I used to do this somewhere else: a nice contact between coarse agpaitic syenite and finer grained metaluminous syenite. The latter includes a mixed mineral assemblage with forsterite and diopside derived from mixing with hawaiitic magmas. #thinsectionthursday #geology #science #minerals #rocks
