Vitória Stone Fair – NEW DATES

Novas datas para a Feira de Vitória – 6 a 9 de Junho 2017

News release just received:

Vitoria Stone Fair | Marmo+mac Latin America 2017 will take place from 6 – 9 June 2017, in Espirito Santo – Brazil. The event is considered the largest stone exhibition in Latin America and the most objective, economical and efficient way to develop business in Brazil, Latin America and the global stone sector.
The fair brings together an exuberant showcase, with several types of materials with colors and unique textures. Also, novelties in machinery, equipment and stone accessories for the industry. The event attracts buyers from all continents, from importers to exporters, looking for machinery, accessories and services.

Guanambi (Bahia, BRAZIL): granite and cacti land

R1F02

Thirteen years ago I travelled into Bahia’s (Brazil) hinterland to evaluate ornamental granite deposits. It was a very short stay (36 hours counting the flights to and from Lisbon).
In following years, I travelled by land to the region (either en route to Chapada Diamantina or as a final destination) but the first impressions of granite massifs and cacti are still vivid (photos here).
It’s a poor region with a beautiful arid nature and warm people. Visit if you can; if not, you may read Jorge Amado’s works (my favourite Brazilian author). Doing both is even better.

If you ever travel there, don’t miss Salvador life and cultural heritage and Bahia’s beaches. Carpe diem.

Going to PDAC – meet and talk

A last minute decision – I am traveling to Toronto to attend PDAC 2016.

It’s the perfect place to meet and talk: Angola, Mozambique, Brazil and Portugal, diamond and other gems, Nb-Ta and other pegmatite minerals, tungsten, gold, ferrous and base metal deposits, industrial minerals, natural stone. Challenges and opportunities.

Where and when can we meet? luischambel@sinese.pt

 

 

Exploração de calcário em zonas cársticas

Guia de boas práticas em discussão pública

Guia_conultaA Sociedade Brasileira de Espeleologia disponibilizou a versão preliminar do Guia de Boas Práticas de Mineração de Calcário em Áreas Cársticas e convida todos a participar enviando críticas, comentários e sugestões.

(a Terra é de todos; neste caso, este Guia está à disposição de todos os falantes da língua de Camões, Pessoa e Vinícius – que todos contribuamos para a versão final com as nossas ideias, comentários e sugestões)

Este Guia é uma importante iniciativa da Cooperação Técnica entre a Votorantim Cimentos, a Sociedade Brasileira de Espeleologia e a Reserva da Biosfera da Mata Atlântica que reafirma o seu compromisso de propor soluções inovadoras para o desenvolvimento económico com responsabilidade social e ambiental.

Elaborado por uma equipa de especialistas de diversas áreas do conhecimento, os seus principais objetivos são a proposta de práticas mais sustentáveis e menos danosas para a atuação das mineradoras em áreas cársticas e permitir a avaliação cíclica do processo de mineração em áreas de karst.

Neste momento, a Sociedade Brasileira de Espeleologia convida todos a partilhar das suas opiniões, sugestões e visões sobre o documento. Para tanto, sugere que usemos a ficha de consulta disponível neste link e encaminhemos a nossa contribuição para o e-mail cooperacaotecnica@cavernas.org.br até dia 03 de janeiro de 2016.

Brazilian Geological and Palaeobiological Sites – Sítios Geológicos e Paleontológicos do Brazil

Brazilian Geological and Paleontological Sites
Certain geological outcrops are specially important either because they either register the origin and evolution of the Earth in those sites, correlated with similar sites in other countries, or because they have exceptional aesthetically value. These GEOLOGICAL SITES deserve to be preserved and publicised.
To protect the rich Brazilian geological heritage and in accordance with UNESCO’s World Cultural and Natural Patrimony Convention, SIGEP – Brazilian Commission of Geological and Palaeobiological Sites, catalogues and describes the Brazilian geological and paleontological sites at http://sigep.cprm.gov.br/
I have already visited some of these sites; they were really worth the trip. Enjoy; seize the day.
It is also worthwhile to read the (chapters that interest you in the) three volumes published but SIGEP about the sites. You may download them at their website or by clicking below.
Sítios Geológicos e Paleontológicos Brasileiros
Certas ocorrências geológicas são especialmente importantes porque registam a origem e evolução da Terra naqueles locais, podendo ser correlacionados com locais de outros países, ou porque apresentam aspectos estéticos excepcionais. Estes SÍTIOS GEOLÓGICOS merecem ser preservados e divulgados.
Para proteger e divulgar o rico património geológico brasileiro seguindo a linha programática da UNESCO de preservação do património natural da humanidade, a SIGEP – Comissão de Sítios Geológicos e Paleontológicos do Brasil cataloga e descreve os sítios brasileiros em http://sigep.cprm.gov.br/
Eu já visitei alguns destes sítios; a viagem vale a pena. Aproveite; carpe diem.
Vale também a pena ler (os capítulos que mais lhe interessam) os três volumes publicados pelo SIGEP. Podem ser descarregados no website do SIGEP ou clicando abaixo.

Characterization, Modeling, Monitoring, and Remediation of Fractured Rock (2015)

21742-0309373727-450A new publication by the NATIONAL ACADEMIES PRESS (pre-publication version just released).
From the book’s summary:

Fractured rock is the host or foundation for innumerable engineered structures related to energy, water, waste, and transportation. Characterizing, modeling, and monitoring fractured rock sites is critical to the functioning of those infrastructure, as well as to optimizing resource recovery and contaminant management. Fractured rock is defined in this report as a mass of rock matrix broken up by fractures. That rock may be crystalline with nominal porosity (i.e., many igneous rocks), or granular with varying amounts of cementation or porosity (i.e., sedimentary rocks)

This report examines new developments, knowledge, and approaches to engineering at fractured rock sites since publication of the 1996 National Research Council report Rock Fractures and Fluid Flow: Contemporary Understanding and Fluid Flow. Fundamental understanding of the physical nature of fractured rock has changed little since 1996, but many new characterization tools have been developed, and there is now greater appreciation for the importance of chemical and biological processes that can occur in the fractured rock environment. Findings in this report can be applied to all types of engineered infrastructure and engineered in situ processes, but especially to engineered repositories for buried or stored waste and to fractured rock sites that have been contaminated as a result of past disposal or other practices. Impacts from artificially induced fractures to enhance hydrocarbon recovery (i.e., hydraulic fracturing) are not part of this report.

Rocks in the sky

No, not the usual meteorites or asteroids. Not even raining diamonds. The Guardian posted it and I had to follow it to the original photo gallery. Enjoy as I did.
