considered that the western and southwestern shores of 
Sviatoy Noss, like most of the other coast-lines of Baikal, 
are approximately parallel to the old strike of the foliated 
and granitized rocks. It was this character that suggested 
E. Suess to designate this kind of displacement as disjunc- 
tive ruptures. The faults bounding the peninsula 
generally are not exposed owing to the fact that there are

rather extensive wave-cut terraces on the Baikal coasts. 
Travelling around the peninsula with a boat along the shore 
one sees almost constantly the lake floor through the 
translucent water of the Baikal, but going a few hundred 
meters from the shore, the ground dips abruptly to depths 
of several hundred, at places more than a thousand meters. 
It is there that the true fault planes are situated. 
Other conditions, however, are prevailing on the shores 
of the Tshivirkouy Bay. Here, around the narrow bay, 
the force of the waves is slighter than on the open shores 
of the Baikal, and therefore the terraces are less extensive, 
Just as the shore cliffs are lower, and traces of terraces from
