Grain boundaries between the quartz and feldspar phases in this sample are consistently lobate, often with finer-grained subgrains rimming each crystal. Quartz in undulatory. The mica phases are subhedral and often resorbed, with kink bands causing undulose extinction along the length of the grain. Along one edge of the thin section is a seam dominated by clinozoisite. A hematite stain gives a dusty orange appearance to the feldspars and fractures within the sample contain higher concentrations of the phase.
Intergrown, subhedral two-pyroxene gabbro with hornblende and poikilitic plagiclase with deformation twins and abundant pyroxene inclusions.
This strongly foliated sample contains mostly hornblende crystals, the alignement of which defines the schistoscity. A granoblastic texture consisting of quartz, and highly poikiolblastic k-feldspar is interspersed among the hornblende grains. Occasional subhedral epidote and calcite grains crop up through the thin section. Of special note are a series of fractures that obliquely cross-cut the foliation; cataclastic textures can be observed along these zones. Small, rounded, colorless to light brown titanite crystals are present.
This thin section consists of two quartz crystals, one of which is oriented perpendicular to the optic axis and provides a perfect crystal with which to obtain an interference figure.
Fine-grained rounded aggregates of chalcedonic quartz set in a matrix of chalcedony and hematite. Veinlets of chalcedony hematite crosscut the sample.
Though dominated by k-feldspar, albite and quartz, this thin section contains biotite pseudomorphs after hornblende, and trace monzaite (distinguished by its high relief, high birefringence colors, and square to diamond shape).
This coarse-grained pyroxenite is comprised of generally euhedral harzburgite crystals. Many crystals are fractured or embayed.
This coarse-grained samples is dominated by subhedral quartzofeldspathic phases. The feldspars are altering to clays and the quartz extinction is undulose. The biotite phase is altering to chlorite in some places and is generally subhedral in shape; kink bands are found in some grains. The hornblende crystals are subhedral and generally cluster with the biotite.
Wards' samples with oriented crystals to show varying 2V angles.
This sample has a granoblastic texture defined by feldspars, garnet, and pyroxene. Crystals of all phases are roughly equant in shape. Alteration is concentrated along the rare hornblende grains and more commonly throughout the pyroxenes. Calcite and apatite are accessory phases and chlorite is found as an alteration product.
Large, interlocking calcite crystals comprise this marble. This thin section is useful for finding interference figures.
This thin section consists of two oriented aragonite crystals, both good for obtaining interference figures.
A large riebeckite grain dominates this thin section.
The hornblende crystals in this thin section are prismatic and subhedral to euhedral in shape. They are strongly aligned. Filling in between the amphiboles are altered feldspars, granular epidote crystals and euhedral apatites.
