Two short tunnels hewn out of the limestone suggest what the road builders were up against.
The proposed chemical weathering and subsequent mechanical erosion of limestone suggest that the development of karst terrain is related far more closely to the geomorphological development of aluminosilicate and siliceous terrains than is generally supposed.
Measurements of the ratio of carbon isotopes types of atoms that have different numbers of neutrons in their nucleus and, therefore, have different weights in the limestone suggest that the site was a spot where methane-rich fluids rose to the sea floor from deep within Earth's crust.
The Fe and Mn concentrations in the type 2 dolomites are higher than those in the type 1 dolomites and the Ma 5 5 submember limestone, suggesting that the dolomitic fluids in the pore water were slightly reducing, incorporating Fe2+ and Mn2+ more easily into the crystal lattice.
The calculated effective porosity at percolation threshold for the limestone sample suggests a minimum requirement on sample porosity in order to form a connected transport path for oil and gas extraction.
The style of the limestone stones suggests a date at the end of the 11th century and that of the sandstone stones around 1100.
The ancient iron formations share many characteristics with modern limestones, which suggests that they accumulated in a marine environment.
On the other hand, the discovery of this new limestone plant also suggests that isolated limestone areas in Taiwan are relatively underexplored and understudied and are a priority for taxonomic work (Peng et al. 2012).
The cellular structure of its wood shows it is a member of the legume family, and the age of nearby limestone outcrops suggest the tree is about 10 million years old.
