小儿发育,或矿物土壤的改变,以纳入有机元素,是一个持续的自然过程。土壤不断形成并改造暴露的天然沉积物,人造沉积物或先前形成的土壤。成土作用引起颜色,质地,成分和结构的变化:在某些情况下,它会产生极其肥沃的土壤,如土地,罗马和中世纪的城市黑土。生物扰动,植物干扰,动物和昆虫的生命,特别难以解释,正如许多实验研究所示,最令人难忘的是Barbara Bocek对口袋地鼠的研究。她发现,口袋里的地鼠可以在一个1×2米的坑中重新填充这些文物,这个坑在七年的时间里用干净的沙子回填。现场埋葬,通过任意数量的自然力量埋葬场地,可对场地保护产生积极影响。只有极少数案例保存完好,就像罗马遗址庞贝一样:美国华盛顿州的Ozette的Makah村庄在公元1500年被泥流掩埋;位于萨尔瓦多的玛雅遗址Joya de Ceren,约公元595年。更常见的是,高能或低能水源,湖泊,河流,溪流,水洗,扰乱和/或埋葬考古遗址。化学修饰也是场地保护的一个因素。这些包括来自地下水的碳酸盐沉积物沉积,或铁沉淀/溶解或骨和有机物质的成岩破坏;和二次材料的产生,如磷酸盐,碳酸盐,硫酸盐和硝酸盐。北美的“庞贝”,Joya de Ceren,于公元595年8月被埋葬在火山爆发中。 Ed Nellis文化变换(C变换)远比自然变换复杂,因为它们包含潜在的无限多种活动。人们建造(墙壁,广场,窑),挖掘(沟渠,水井,私人),放火,耕犁和粪肥田地,最糟糕的是(从考古学的角度来看)他们自己清理干净。为了处理过去所有这些模糊遗址的自然和文化活动,考古学家依赖于一组不断增长的研究工具:主要的是地质考古学。地质考古学是一门与自然地理学和考古学相结合的科学:它关注的是理解场地的物理环境,包括它在景观中的位置,基岩和第四纪沉积物的类型,以及土壤内外的土壤和沉积物的类型。现场。地质考古技术通常借助于卫星和航空摄影,地图(地形,地质,土壤调查,历史)以及地磁物理技术(如磁力测定)来进行。

澳大利亚悉尼科技大学论文代写:小儿发育

Pediatric development, or changes in mineral soils to incorporate organic elements, is a continuous natural process. The soil continuously forms and modifies exposed natural deposits, man-made sediments or previously formed soil. Soil formation causes changes in color, texture, composition and structure: in some cases it produces extremely fertile soils such as land, Roman and medieval urban black soil. Bioturbation, plant disturbances, animal and insect life are particularly difficult to interpret. As many experimental studies show, the most memorable one is Barbara Bocek’s study of pocket hamsters. She found that the hamsters in the pocket could refill these artifacts in a 1×2 meter pit that was backfilled with clean sand for seven years. Burial on site, through any number of natural forces burial sites, can have a positive impact on site protection. Only a few cases are well preserved, like the Roman site Pompeii: the Makah village of Ozette in Washington State was buried in the mud in 1500 AD; the Maya ruins in El Salvador, Joya de Ceren, around 595 AD. More common are high-energy or low-energy water sources, lakes, rivers, streams, washed, disturbed and/or buried archaeological sites. Chemical modification is also a factor in site protection. These include carbonate deposits from groundwater, or iron precipitation/dissolution or diagenetic failure of bone and organic matter; and secondary material generation such as phosphates, carbonates, sulfates and nitrates. North America’s “Pompei”, Joya de Ceren, was buried in a volcanic eruption in August 595 AD. Ed Nellis cultural transformations (C transformations) are far more complex than natural transformations because they contain potentially unlimited activities. People build (walls, squares, kiln), excavations (ditches, wells, private), arson, ploughs and manure fields, and worst of all (from an archaeological point of view) they clean themselves up. To deal with the natural and cultural activities of all these vague sites in the past, archaeologists rely on a growing set of research tools: primarily geological archaeology. Geological archaeology is a science that combines physical geography and archaeology: it focuses on understanding the physical environment of the site, including its location in the landscape, the types of bedrock and Quaternary sediments, and the soil inside and outside. The type of soil and sediment. on site. Geological archaeological techniques are usually carried out by means of satellite and aerial photography, maps (topography, geology, soil surveys, history) and geomagnetic physics techniques (eg magnetometry).
