Statements
1,750 to 1,900 metre thick sequence of Upper to Lower Cretaceous mafic to felsic volcanic and volcaniclastic
subvolcanic stocks and dykes related to episodes of Cretaceous volcanism are present in the succession. The
volcanic-volcaniclastic sequences ranging in age from Lower to Upper Cretaceous. The oldest, the Lower Cretaceous
Cretaceous. The oldest, the Lower Cretaceous lvaninsky Sequence, is subdivided into
Unconformably overlying the above units is the Lower Cretaceous Engterinsky Sequence, a 250 to 300 metre
unconformably upon the previous sequence. It comprises Lower Cretaceous amygdaloidal pyroxene-bearing andesite
2003 youngest sequence, the Makinsky Sequence, is Upper Cretaceous in age and consists of rhyodacite tuffs
intrusive rocks range in age from Lower to Upper Cretaceous. There are four known ages of dykes and
porphyritic diorite dykes which are confined to the Lower Cretaceous lvaninsky Sequence and older sedimentary
from rhyolitic to dacitic in composition. An Upper Cretaceous age is assigned to these dykes. The youngest
are diorite dykes and stocks of the Upper to Lower Cretaceous Okhotsky Complex. In the Julietta area
the Bulat Caldera System, which is related to the Cretaceous volcanic activity. The caldera subsidence
margin, juxtapose the Jurassic sediments and the Cretaceous volcanic rocks. A domal feature, termed
veins. The gold-silver mineralization at Julietta is Lower Cretaceous in age and is low temperature epithermal
a 1,600 metre thick succession of Upper to Lower Jurassic terrestrial sedimentary rocks. A variety
Cretaceous volcanism are present in the succession. The Jurassic sedimentary rocks may be subdivided into
area is a 650 to 750 metre thick succession of Lower Jurassic coarse grained siltstones and sandstones
overlying this sequence is a 250 metre thick Lower Jurassic sequence of interbedded siltstone and argillite
faults, which, at the caldera margin, juxtapose the Jurassic sediments and the Cretaceous volcanic rocks.
