CROSS-FIBRE CHRYSOTILE. THE MORE PERSISTENT JOINTS TEND TO CONTAIN
THE WIDER VEINS, WHILE MYRIAD SMALLER FRACTURES ARE FILLED WITH
SHORT—FIBRE VEINLETS. THE ORIENTATION OF JOINT SYSTEMS WITHIN
SUCCESSIVE BLOCKS VARIES WIDELY BUT TENDS TO FAVOUR TWO GENERAL
DIRECTIONS, ONE TRENOING NORTH-NORTHWEST TO NORTH=NORTHEASTS THE

OTHER ABOUT EAST-SOUTHEAST. DIPS VARY FROM SHALLOW TO STEEP IN

ETHER DIRECTION.

»
Most VEINS ARE A-COMPOUND OR "Two-FIBRE" TYPE, WITH A

CENTRAL PARTING, BUT THESE MAY CHANGE ALONG STRIKE TO SIMPLE OR
None=-FiBsReE" vEINS. MOST ARE LENTICULAR OVER SHORT DISTANCES, BUT:
SOME PERSIST FOR DOZENS OF FEET. SOME COMPOUND VEINS ARE FORMED
BY THE MERGING OF TwO SIMPLE VEINS COMING TOGETHER FROM DIFFERENT
DIRECTIONS. SHORT LANDER VEINS ARE COMMON. ON THE OTHER HAND, IT
1S POSSIBLE TO FIND AREAS EXPOSED IN THE PIT CONTAINING FIFTY
PARALLEL VEINS, AT ABOUT ONE=FOOT SPACING, ALL TEN FEET OR MORE IN

LENGTH AND OVER ONE-HALF INCH IN WID THe

THERE ARE Two EXCEPTIONS TO THE GENERAL RULE THAT THE
MASSIVE SERPENTINE MAKES ORE AND THE SHEARED SERES Ta 1S WASTEs
THE OREBODY CONTAINS ZONES OF POST—ORE SHEARING, 1N WHICH LONG
FIBRE VEINLETS HAVE BEEN DRAGGED, SQUEEZED, BENT, AND PARTLY

CONVERTED TO TALC. THESE ZONES STILL CONTAIN A HIGH PERCENTAGE

OF LONG FIBRE, ALTHOUGH IT TENDS TO CREATE OUST IN MILLING.

THE OTHER EXCEPTION !S THE MASSIVE SERPENTINE TOWARDS THE
HANGINGWALL AND NORTH END OF THE OREBODY, WHERE APPARENTLY THE

STRESSES WERE WEAKER ANDO FEWER FRACTURES WERE FORMED. THE ROCK

* CONTAINS A LOWER TOTAL PERCENTAGE OF FIBRE AND THE VEINS ARE

NARROWER. IT ALSO CONTAINS A LARGER PERCENTAGE OF "nasTiITes"™
