ranging from shades of brown to shades of blue

Petrology, also known asthe study of rocks, is the science of the formation, properties, and uses ofrocks. In our online series, we introduce different types of stone and their occurrences: This time, Palissandro Bluette.

Palissandro Bluette is a dolomitic marble. Compared to calcitic marbles, which consist primarily of the mineral calcite—such as Carrara marble—dolomitic marbles exhibit greater resistance to chemical and mechanical stress. Dolomite marbles consist primarily of the minerals dolomite and calcite. However, dolomite marbles may also contain other minerals that contribute to their decorative appearance.

In the case of Palissandro Bluette, this is the phyllosilicate (layered silicate) phlogopite. This mineral belongs to the group of mica minerals and formed during the metamorphic transformation of the rock. In Palissandro Bluette, it occurs in small flakes, most of which are no larger than one millimeter. In the field of natural stone, phlogopite is relatively rare as a decorative mineral. Nevertheless, it is found throughout the Earth’s crust worldwide. These layered silicates can also vary greatly in size. For example, a phlogopite five meters in diameter was discovered in the Irkutsk region of Siberia.

Alpitecture – Tourism architecture

Building design

A look behind the scenes: This year, Alpitecture is combining excursions in South Tyrol with an architecture competition on the subject of tourism architecture.

This year’s “alpitecture code 7-15” combines exciting excursions in South Tyrol and an architecture competition with an informative congress on the topic of “tourism architecture”. The events are organized by local companies and allow participants to take a look behind the scenes of South Tyrolean companies. Baumeister is a media partner.

The focus is on tourism architecture and its impact and influence on the respective location and people. In three program points, the question of what characterizes attractive and successful tourism architecture will be discussed. How are architecturally attractive destinations created? What architectural features and impressions attract tourists? How can they remain popular tourist destinations for years to come? Thus, the two players “architecture” and “tourism” form a symbiosis of two promising, exciting worlds.

Alpitecture Tour

This year, three independent architecture excursions will be offered from 11 – 13 June – in the regions of Bolzano, Val Pusteria and Valle Isarco, which are characterized by their distinctive and unusual architecture. In addition to selected architectural highlights, the “alpitecture summit” (see below) will be visited on Friday.

Alpitecture Award

This year for the first time, the EOS – the Export Organization South Tyrol – is presenting the Alpitecture Award on the subject of “Tourism Architecture” for architects and interior designers. The competition focuses on architectural projects that provide measurable added value for tourism, its users, visitors and guests. Projects realized between 2008 and 2014 are eligible. The participation phase ends with the last possible submission on May 29, 2015. An international jury led by Hain Rashid from Asymptote Architecture and Todd Saunders from Saunders Architecture will award prizes to the submissions. All projects will be on display in an exhibition at Museion Bolzano on June 12 during the Alpitecture Summit.

Alpitecture Summit

The series of events will be rounded off with the Alpitecture Summit on June 12. This congress will once again take up the theme of the Alpitecture Award “Tourism Architecture”. It will focus on the central idea of how architecturally attractive and successful destinations are created.

Speakers and jury members are Hani Rashid (Asymptote Architecture), Todd Saunders (Saunders Architecture), Jürgen Mayer H. (J. Mayer H. und Partner), Wolfram Putz (Graft), Werner Frosch (Henning Larsen Architects)

The Summit is a public event and can be attended independently. To register and for further information, please visit the website at www.alpitecture.com.
