Miocene to Pleistocene sand and sandstone were recovered at Ocean Drilling Program Site 974 in the Tyrrhenian Basin and Sites 976 and 977 in the Alboran Basin. Sand detrital modes were determined for 45 samples from these sites, as well as 10 samples of Spanish beach sand. At Site 974, the Pleistocene section includes a number of volcaniclastic (vitric ash) and terrigenous sand layers; the latter are heterogeneous and contain sedimentary and metamorphic lithic fragments. Submarine canyon and onshore drainage patterns suggest that the most likely source of this sediment is the Tiber River drainage basin in central Italy, where a Pleistocene volcanic field is superimposed on Apennine orogenic rocks. In contrast, the Miocene sand in Unit III at Site 974 may have been derived from local basement highs. The quartzolithic composition and preponderance of metamorphic and sedimentary lithic debris in sand samples from Unit II at Site 976, Unit I at Sites 977 and 978, and Unit I at Site 979 are consistent with derivation from metamorphic rocks and sedimentary cover sequences that crop out in the Betic Cordillera of southern Spain (976-978) and in the Rif of Northern Africa (979). The sedimentary to metamorphic lithic fragment ratios in these samples reflect the relative proportion of metamorphic and sedimentary rocks exposed in onshore source terranes. In contrast, the source of the few quartzose Pleistocene sands at Site 976 was likely the Flysch Trough Units that crop out near Gibraltar. The significant volcanic component in certain intervals at Sites 976 (upper Miocene) and 977 (lower Pliocene to Miocene) is consistent with widespread volcanic activity during basin inception and development. Mean sand detrital modes for sand subgroups from both the Alboran and Tyrrhenian Basin sites plot in the Recycled Orogenic and Magmatic Arc compositional fields of Dickinson et al. (1983, doi:10.1130/0016-7606(1983)94<222:PONAPS>2.0.CO;2), reflecting the hybrid tectonic histories of these basins.

O Artigo 12º do projeto da Comissão de Sistematização, que trata dos direitos do homem e da mulher, é um dos que tem recebido grande número de emendas. O Deputado Bernardo Cabral (PMDB-AM) comenta sobre as emendas. Informações sobre requisitos para validar as emendas populares. O Senador Fernando Henrique Cardoso (PMDB-SP) informa que nunca no Brasil houve uma Constituição com tanta participação popular. O Deputado Aldo Arantes (PC do B-GO) afirma que a mobilização popular e a pressão democrática são necessárias para que possamos ter uma Constituição avançada, pois os grupos conservadores exercem muita pressão na Assembleia Nacional Constituinte (ANC). Orestes Quércia, Governador de São Paulo, diz que é preciso que todos, de alguma forma, participem do processo de elaboração da Constituição. Engenheiros debatem propostas com os constituintes. Mateus Schneider, Presidente do Clube de Engenharia, esclarece que a intenção é contribuir com informações técnicas aos constituintes, deixando de lado a questão ideológica. O Deputado Flávio Palmier (PMDB-RJ) comenta que o Clube traz ideias para dialogar com os constituintes, sem se colocar como lobista. Propostas do Clube: definição de empresa nacional, proibição dos contratos de risco, reserva de mercado para informática, defesa dos recursos minerais do país. A Deputada Raquel Cândido (PFL- RO) considera que a proposta mais interessante dos engenheiros diz respeito à industrialização de matérias-primas no país. O Deputado Nelson Seixas (PMDB-SP) considera que o Brasil deve expandir as reservas de mercado.

Dinuclear complexes [Mo-2(mu-pyS)(2)(CO)(4)(PPh(3))(2)] (1), [Mo-2(mu-pyS)(2)(CO)(5)(PPh(3))] (2) and a trace quality of trinuclear complex [Mo-3(mu-pyS)(2)(mu(3)-pyS)(2)(CO)(6)] (3) were obtained from the reaction of [Mo(CO)(3)(MeCN)(3)] with pyridine-2-thione (pySH) and PPh(3) in THF. The crystal structures of 1.2C(7)H(8) and 3.7 C7H8 have been determined by X-ray diffraction studies. Crystals of 1.2C(7)H(8) are monoclinic, space group C2/c and Z = 4, with a = 18.797(3), b = 11.143(4), c = 28.157(7) Angstrom, beta = 101.23(2)degrees. The structure was refined to R = 0.050 and Rw = 0.057 for 3146 observed reflections, Crystals of 3.7 C7H8 are monoclinic, space group P2(1)/a and Z = 4, with a = 13.912(2), b = 17.161(2), c = 15.577(3) Angstrom, beta = 101.17(1)degrees. The structure was refined to R = 0.046 and Rw = 0.051 for 4357 observed reflections. The molecule of 1 consists of two Mo(CO)(2)(PPh(3)) fragments linked by an Mo-Mo bond (2.974(2)Angstrom) and by two doubly-bridging pyS ligands. The compound 3 contains a bent open geometry of three molybdenum atoms (Mo(1)-Mo(2)-Mo(3) angle 122.99(3)degrees) linked by two Mo-Mo bonds (2.943(1) and 2.950(1) Angstrom) and by two doubly- and two triply-bridging pyS ligands.
