Vesicles	<0.5	<0.2		Clay linings	Round		        							        											Alteration minerals, from edge of halo inward toward site of fracture: 1) Small amounts of olive-green, low-birefringent clay. Partially replaces mesostasis, with an associated more general brown discoloration of the mesostasis.				2) A variety of yellow to orange birefringent clays. Commonly forms fringes on scarce vesicles, replacing mesostasis. Also fills microfractures. Associated red-orange, non-birefringent "Fe hydroxide" +/- birefringent clay forms globular masses up to				0.2 mm (gives gray reflective polished surface) and irregulart replacements of mesostasis.				3) A zone at least 2-3 mm wide along the edge of the section nearest the fracture has relatively little distinctive alteration material (very sparse, mainly Fe hydroxide). Reflected light shows that the mesostasis is in fact pervasively altered to a				soft (hydrated) material.													Interesting groundmass textures: 1) Elongate ol in optical continuity extended for up to 3 mm parallel to the c-axis, forming sub-poikilitic relationship to plag. Locally overgrown by intergranular cpx in near optical continuity with ol. Similar elongated ol extends in continuity from the 1 mm equant ol phenocryst, with rods of the same crystal extending 0.1 mm into enclosing cpx and plag (cpx is not in optical relation to ol). Some ol ,oikocrysts partially enclose and interpenetrate a plag lath orientated parallel to the c-axis of ol. More equant, sub-poikilitic to intergranular ol is common in the vicinity of the 1-mm sized ol phenocryst. 2) "bow-tie" structures: rare occurance defined by intersecting plag laths and by a gap in plag enclosed in ol oikocryst. 3) Rare hollow subhedral olivine crystals enclosing plag and mesostasis.	no	22.92200	-44.94708	0034.80	3479
