In this context, the sedimentites that crop out near the mouth of the Chocorí Creek contain a set of palaeontological sites that, because of their richness and well-preserved fossil content, hold high national and international importance.
Limestone has long fascinated earth scientists because of its rich fossil content.
Sedimentologists study the constituents, textures, structures, and fossil content of the deposits laid down in different geographic environments.
The most useful indication of time equivalence is similar fossil content, provided of course that such remains are present.
Any feature, including colour variations, textures, fossil content, mineralogy, or any unusual combinations of these can be used.
Wind energy is a hedge against higher fossil fuel prices.
Hydrogen (H2) is considered a clean source of energy and an ideal substitute for fossil fuel owing to its high energy content (122 kJ/g), recyclability and non-polluting nature.
Although there are still some difficulties in hydrogen commercialization, such as high production costs, technical storage, and distribution [ 1], biohydrogen production is exhibiting perhaps the greatest potential as an alternative to fossil fuels [ 2] because of its clean, high energy content per unit of weight (142 KJ/g) and zero greenhouse gas emissions generated by oxidative combustion.
Biomass has proven to be less efficient and more cost intensive compared to the current fossil fuel processes, due to its relatively low energy density, high moisture content and distributed-resource.
But the reign of coal, which has the highest carbon content of all fossil fuels, has resulted in unintended consequences, from local air pollution to global climate change.
