In Lithuania geochemical mapping of urban areas was started in Vilnius city in 1985. Topsoil, stream sediments, snow cover, manufactory dust and other sampling media are used in ecogeochemical investigations. The aim of investigations is to detect sources of pollution, its geochemical properties and spread of its contamination. Furthermore, a sanitary assessment of urban soil is carried out on the basis of available geochemical data and the soil quality standard of Lithuania HN 60:2004. The soil contamination with heavy metals is estimated according to the highest allowable concentrations (HAC) and the total contamination index Zd which is related to the criteria of human health. At present the geochemical data on soil contamination in the areas of Vilnius, Panevëžys, Mažeikiai, Šiauliai, Alytus, Biržai, Pasvalys, Rokiškis, Kupiškis and other towns are in store of the geochemists of Geological Survey of Lithuania and Institute of Geology and Geography. The soil geochemical background values obtained by geochemical mapping of natural areas are always used for assessment of contaminated urban areas. Part of geochemical background and contamination data is published in Geochemical Atlas of Lithuania. Some geochemical data and soil contamination maps are in use of town municipalities on order and funds of which the geochemical investigations of urban areas were performed. However, geochemical investigations lag behind the planning, development and reclamation projects of urban areas, thus, new dwelling houses are often built on hazardous contaminated sites that may make a threat against human health.

The presence of spatial magma heterogeneities in volcanic monogenetic fields is a major observation discussed as well synthesized for worldwide volcanic fields. Magma heterogeneities still have not been visualized in the form of detailed spatial analyst tools, which could further help structuring works of geological mapping, volcanic hazard, and geoheritage evaluations. Here we synthetized 32 published datasets with a novel geochemical mapping model inspired by sub-disciplines of geomatic in one of the most documented monogenetic fields on earth: the Chichinautzin Volcanic Field (CVF) in Mexico. The volcanic units from CVF are covering the 2500 km2 area, and its neighbor stratovolcanoes are bordering the limit of most volcanic centers (Popocatepetl, Iztaccihuatl, and Nevado de Toluca). The results illustrate polygons and point map symbols from geochemical markers such as Alkalis vs SiO2, Sr/Y, and Ba/Nb. The geochemical heterogeneity of the CVF monogenetic bodies decreases as it approaches the Popocatepetl-Iztaccihuatl stratovolcanoes. This alignment is not observed in the occidental CVF portion near the flank of Nevado de Toluca, but geochemical anomalies associated to markers of continental crust interaction such as Sr/Y follow elongated patterns that are not strictly following structural lines and faults mapped on surface.

Reconnaissance geochemical mapping by means of stream sediment and water has been carried out by the Geological Survey of Greenland (GGU) in West and South Greenland since 1979 (Steenfelt, 1987, 1993). The aim of the programme is to evaluate the potential for mineral resources. The geochemical data are used in two ways: (1) to identify chemical anomalies indicative of mineralisation; and (2) to contribute to the recognition of environments favourable to ore deposition. However, when compiled over large areas the data also permit a distinction to be made of large scale crustal domains.

The 1960S

A vibrant American Indian art scene developed in California from the 1960s to the 1980s, with links to a broader indigenous arts movement. Native American artists working in the state produced and exhibited paintings, prints, sculptures, mixed media, and other art forms that validated and documented their cultures, interpreted their history, asserted their survival, and explored their experiences in modern society. Building on recent scholarship that examines American Indian migration, urbanization, and activism in the twentieth century, this article charts these developments and argues that American Indian artists in California challenged and rewrote dominant historical narratives by foregrounding Native American perspectives in their work.

Arts Festival Negari Ngayogyakarta Hadiningrat 2012 undertaken in order to commemorate the first century of Hamengku Buwono IX as well as 2,5 century of Ngayogyakarta Hadiningrat, featuring the character or the privilege of Yogyakarta through works of art by artists with no exit from the corridors of copyrighted artistic distinctiveness. The works on display most of the particular character, specific and have their own specialty. Privileges of Yogyakarta with its dynamic, multicultural, and tolerant of the works reflected on display in the various mediums of expression and creation. A wide assortment of works of art displayed expression of both the traditional, conventional and non conventional, such as: painting, graphics, sculpture, video, film, animation, installation, performance art, digital prints, puppets, mixed media and others. Not to mention that the exhibition has a variety of craft works of art, such as the art which haselements of craftmanship. The uncommon art that relies on creativity ideas and handskills in this exhibition appear surprisingly with exceptional works that have creative potential prospective. These young artists, among other craft; Karyadi, Fitriasih Pudyo Atmaningrum, I Gde Suryawan, and I Gusti Ngurah Edi Basudewa.Keywords: potential, arts crafts, specialty, and Negari Ngayogyakarta Hadiningrat
