This “fast” strategy offers the advantage of the efficient use of abundant resources, enabling plants to outcompete those following the “slow” strategy. On the other hand, this “slow” strategy facilitates survival under conditions of limited resources and low growth capacity [61,67,68,69]....
This is evidenced by the presence of dispersed carbon, which is abundant in the sedimentary–volcanogenic strata of the region. The mountain systems surrounding the closed, shallow water basin led to the sedimentation of erosion products of the tonalite– trondhjemite and amphibolite–komatiite rocks ...
