  1. A pegmatite is an #igneousRock showing a very coarse #texture, with large interlocking #crystals usually greater in size than 1 cm (0.4 in) and sometimes greater than 1 meter (3 ft). Most pegmatites are composed of #quartz, #feldspar, and #mica, having a similar #silicic composition to #granite. However, rarer #intermediateComposition and #mafic pegmatites are known. Many of the world's largest crystals are found within pegmatites. These include crystals of #microcline, quartz, mica, #spodumene.

  2. Feldspar releasing debut album ‘Old City, New Ruins’ on September 30

    Italian rockers Feldspar will release their upcoming debut LP, Old City, New Ruins on September 30th via TTK Records.

  3. @Paperposts Now can you decode this for us? my guess is foliated metamorphic rock (banded appearance) with #quartz and #feldspar. Given that this is the Marin Headlands, these are probably marine layers pushed up by tectonic plate movement. Or, I'm all wet.

  4. Twinned #feldspar crystals
    In a paving stone in #Exeter, United Kingdom, pound coin for scale.
    Must have cooled slowly, allowing large crystals to grow, so #intrusive, not #extrusive / #volcanic.

  9. Sort of #selfPortrait in #QuincyGranite

    The spectral form, like Jesus looming out of a piece of toast, is me, taking a #photo of a circa 1.5 meter polished granite sphere in the #MountWollastonCemetery in #Quincy. The largest visible #crystals (#feldspar and #amphibole) are about 1 centimeter across.
