Some mobs within the mod can spawn with random mob names, which is an easter egg in the mod.īelow are the available random names that a certain mob can spawn with. The mod is mainly focused its added dimension that introduces various arthropods, dungeons, enhanced biomes and unqiue blocks and items.Īn in-depth magic and farming system is planned for future versions of the mod, as well as much more content. For allegedly older samples K-Ar is used to "date" the standard and as such it still has the same problems as K-Ar dating.The Erebus is a mod led and developed by Dylan4ever along with the rest of The Erebus Team. If the standard is of historically known age, such as would likely be used for testing Ar-Ar dating on sample of known age, then one would be more likely to get the correct age. One key factor is the fact that Ar-Ar dating needs a standard of "known" age. Now in all fairness Ar-Ar dating can get the right age for a sample of known age, but it can also date samples as way too old, but without a known date there is no way of knowing when it is too old. So if these are real dates then you can hold a rock in your hand that won't form for hundreds of thousands or even millions of years yet. K-Ar and Ar-Ar can result in negative ages when atmospheric argon is considered. Isochron dating can also produce negative ages, by producing a negative slope. Some rocks have been measured with negative radiometric ages, in some cases in terms of millions of years.

Recent or young volcanic rocks producing excessively old K-Ar "ages":įrom: Potassium-Argon and Argon-Argon Datingįrom: G.B. Some rocks dated older than the 4.5 billion year evolutionary age for Earth. It was explained by the processes of heating and cooling that the soil had been through. Some soil from the Moon has been dated as more than a billion years older than the uniformitarian age for the Moon. Some times radiometric dating produces impossible results.Īge Inconsistencies extremes in billions of Years Quick cooling or not having contact with the air can affect theoretical mechanisms for "resetting" the clock. The conditions of formation are also important, because both the cooling rate and the opportunities for mixing affect isotope ratios. The isotopic make-up of original material is important, as is mixing of magma with surrounding material. How a rock is formed is important to understanding its isotopic make-up and any dates derived. This is particularly important in light of the Biblical flood. His name is used interchangeably with Tartarus and Hades since Erebus is often thought of as part of the. Water flow through rocks is important because all parent substances and many daughter substances are water soluble. In Greek mythology, Erebus (pronounced: rbs), also Erebos (Ancient Greek:, 'deep darkness, shadow'), was the son of a primordial god, Chaos, and represented the personification of darkness and shadow, which filled in all the corners and crannies of the world. Evidence for Isotopic Fractionation does show up in isotopic data so it is a factor that needs to be considered. It can be caused by heating and cooling, water flow, contact between high and low concentration magma and just normal molecular motion. Isotopic Fractionation is a physical separation of isotopes and a non-radioactive source of isotope ratios. Sometimes these are close but other times they are very different. Furthermore, the same method can produce different ages on different parts of the same rock.
Sometimes different methods used on the same rock produce different ages. However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock.
In short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample. To date rocks or other objects, scientists typically use radiometric dating.
