The ignimbrite flare-up is the event which took place some 25 to 40 million years ago, which involved the volcanic activity. This eruption took place in the western United States. The Ignimbrite Flare-Up produced a large massive amount of the volcanic ash as well as the lava. As a result, there have been many questions which have risen over the origin of the volcanic rocks which formed the Rocky Mountains and what forces might have caused its uplift. The timing of the Rocky Mountains uplift has therefore been attributed to the presence of ignimbrite flare-up, which is considered as the main factor in the eruption or the uplift.
The voluminous ignimbrite flare-up is said to have affected the western North America during the mid-Tertiary remains. This was one of the major continental igneous event that took place several years ago. The major source of the mafic magmas in the southern Rocky Mountains was the lithospheric mantle. In the northern part of the Mexico during the mid-Tertiary, the effect of silicic composition was much felt as it was wide spread (Farmer et al, p 280). At this point, the ignimbrite flare up was much voluminous as well as long-lived. Since then, it have been so difficult to constrain the composition of the volcanic rocks because of erosion and the burial of the younger ignimbrite. It has only remained to be estimated since the exact figure could not be established because of the erosion as well as the burial of the ignimbrite.
Since the composition of ignimbrites vary from the phenocryst-poor that constitute about 5-10 % in the volume of crystal, it is therefore easier to use it in estimating the timing of the Rocky Mountain uplift (Farmer et al, p 281). The younger ignimbrite has a volume of up to 20K km3 which is almost a half of the older of that intermediate composition of the volcanic rocks. It is also easy to distinguish between the crystal poor rhyolites and that of the crystal-rich dacites at the SJVF. This information can be used to estimate or rather to represent the re-mobilization of the previously generated igneous materials that formed the Rocky Mountains.
The eruption of the crystal mushes which are rich in ignimbrites flare ups contains some isotopic compositions that overlaps the ones that are older intermediate composition. This overlapping can as well be used to establish the uplift of the Rocky Mountains. In this case, the ignimbrites becomes more significant in estimating the timing of the uplift of the Rocky Mountain. The Isotopic Data that is found from the ignimbrites which is throughout the Rockies has also enabled to estimate the crystal components in the rocks. Despite this, it is highly dependent on the isotopic compositions. With this information, it is easy to establish the timing of the uplift of the Rocky Mountains.
The ignimbrite flare up can be linked to the refrigeration as well as the hydration of the pre-existing mantle. The removal of this oceanic plate from the beneath of the southern Rocky Mountain region could give rise to a proper timing of the Rocky Mountain uplift (Farmer et al, p 285). Through estimating the volume of ignimbrite flare up, it is easy to establish the timing of the uplift of the Rocky Mountain, since its composition can also be established.
