The quartz veins of the Svetllnek deposit poeeeee a lentioular
form frequently rather complex. The etrike of the veins ie meri-
dional and conformable with the eahietosity of the enclosing rooks;
the dip is opposite to the quart z-mioaoeous eohiste. The angle of
intersection of the vtinA and rooks varies between the limits 600
to 860. The wa11e of the veins are rather irregular; aoute-angled
boundaries of rook are often observed in the form of inclusions in
the vein quartz. The length of the quartz aooording to strike and
dip varies within wide limits. Judging from the form and conditions
of the beds where the veins occur they are full of fissures.
