This paper focuses on the representation of horses graved on rocks in the Mouro River basin (NW Portugal), an afluent in the south margin of the Minho River. The objectives are the study of its distribution in space, in relation to physical characteristics; the specificity of types of graved horses; the characteristics of the rocks graved by group of horses; the orientation of horses by type and their disposition in the rock compared to other graved motifs.

Original Concept

Metahadzia uncispina n. sp. is described, being the second species of the genus on the Iberian Peninsula. The new species, well characterized by the transformation of the apical spine on the endopodite of the male uropod 2, is undoubtedly closely related with M. tavaresi (Mateus & Mateus, 1972) from the south of Portugal. Comments are made about recent emendations of the original concept of the genus Metahadzia Stock, 1977.

Soil-cement bricks are good examples of environmentally friendly products. This brick is the combination of soil with compacted cement with no combustion in its production. In this work the physical chemical characteristics of the soil from Piaui for producing this material were investigated. Samples of the soil were collected in three potteries from the county of Bom Jesus and pH analysis were carried out, as well as the rate of organic matter, texture, particle density, limits of liquidity and plasticity rates. The results have shown that the soils have acid tones (pH 5,49 a 6,11), which can be neutralized by adding cement, and organic matter percentages up to 1%. The samples have shown predominantly clay-rich textures with adequate plasticity limits, however, values of liquidity limits and particle density above recommended. Altogether, these soils tend to present viability concerning soil-cement brick production, provided that corrections with additives are made in order to minimize this effect.
