PETROLOGIC DATA

Rock Number: 1

Rock Type: arenite
Field Description:

-section continues from north to south at the southern extremity of station 5410
-abrupt change from massive unsorted, ungraded conglomerate into variable section approximately 75 metres of cross bedded quartz arenite conglomerate and trough conglomerates
-grading is prominent but slightly variable, tops apparently south
-this passes rapidly into another thick section of massive unsorted, ungraded conglomerates similar to previous units unit the last 60 metres of outcrop when there is a sudden increase in mafic components, basalt clasts of boulder size increase in abundance of garnet
-this would seem to indicate a possible closure and we're now moving down section towards basalts
