Figure 3. (a) The structure of the serpentinite melange area in the thalweg of the Yanas-Keu-Lek-Talba
Creek: (1) alluvial deposits; (2) schistose siltstone and sandstone;
(3) serpentinite melange; (4) ophycalcite;
(5) gabbro, gabbro amphibolite; (6) quartz diorite and plagiogranite;
(7) stepwise intersecting diabase dikes (sills);
(8) dips and strikes: schistosity in
the serpentinized melange (a) and in the sedimentary rocks (b);
(9) the position of the area shown in Figure 3b.
(b) A segment of the melange block composed of gabbro-amphibolite grading via amphibolized
quartz diorite to plagiogranite, one can see the intersections of thin diabase dikes and sills:
(1) diabase, (2) gabbro and gabbro amphibolite,
(3) amphibolized quartz diorite and plagiogranite.
