Examine the geology of the Round Island thoroughly.
On the south and South west the predominant rock is a hard bluish sandstone (A) with a variable dip, (near the shore SW 64�.) from nearly level to perpendicular. containing large clayey nodules and showing the effects of heat & great pressure - with a tendency to split into cubical or acute angled six sided blocks or fragments. To the south a fault in the strata occurs on each side of which (C) the rock is broken into very small pieces which are united together with a matrix of yellowish calcite and thin veins of chalcedonic and drusy quartz to the east of the
