Inclusion trails defining S1 planes deformed by F2 folds preserved in garnet porphyroblast. Kamieniec Metamorphic Belt, Fore-Sudetic Block.
Complex garnet porphyroblast. Its
inner part preserves inclusion trails, composed mainly of rutile, defining S1 planes (early garnet
generation – Grt1). Rim part contains younger S2 planes, composed mainly of ilmenite (late garnet generation – Grt2). Notice that S2 planes
continue into the matrix of the rock. Kamieniec Metamorphic Belt, Fore-Sudetic Block.
Quartz grains showing different types of
cathodoluminescence (CL) zonation patterns. Left: normal zoning with
bright CL core and darker CL toward the rim. Take a note of irregular
shape of internal parts of the grain. Right: reverse zoning with darker
CL core region and brighter CL outer rim. Look at various shape and
depths of embayments which crosscut outermost rim zone. The lobate and
rounded form of mantle-rim zone boundary indicates simultaneous growth
of zones around gaseous bubbles attached to the mineral interface (upper
and right embayments).
Cathodoluminescence images of silicic plutonic (left) and volcanic (right) rocks. Take a note of different accessory minerals associations of apatite (bright green) and zircon (bright white-blue)
Layering in silicic plutonic rocks in
micro-cathodoluminescence image. Transitional region is highlighted by
change in modal (variable mineral modes) and textural (grain-size)
layering.
Electron microprobe X-ray chemical maps of garnet. Boundary
between garnet I (core) and garnet II (rim) is marked by Ca depletion and
Y-annulus. Garnet I shows progressive zoning pattern with bell-shaped Mn.
