Marinace: the riverbed of stone

marinace"Marinace belongs to the category of Brazilian granites. In our warehouse you’ll find Marinace Rosso, besides the already mentioned  Marinace Gold, Marinace Nero and Marinace Verde. When we were kids, we had to fetch fire stones from the river Adige, whenever the water flow was calm and the level low. We moved on a broad beach made of rounded pebble stones, grey and sandy mud and moss. This event comes in my mind when I contemplate Marinace Verde,  Marinace Nero or Marinace Gold."

Depending on the type of Marinace, thousands of petrified pebbles in every size and colour  are highlighted on a homogenously coloured background. Look at the photos and try to get used to the idea that Marinace is not an artificial, but a completely natural material. It is not produced, at least not by human hands. Humans lend a hand to mine, to cut and to polish this stone… Marinace, due to its attributes, should belong to the category of granite. It’s a very hard stone, even harder than granite and weatherproofed as granite…

… but, actually, it is not granite, not an igneous rock. Marinace is, indeed,  a conglomerate and all types of conglomerates are sedimentary rocks, consisting of rounded gravel (so called „clastic sedimentary rocks“)  which are naturally cemented with a fine-grained material called matrix by the geologists. 

Marinace is a polymict - conglomerate, it is composed of pebbles in different sizes.  These pebbles are made of different minerals. The stone’s characteristic structure depends on the glacial erosion.  Imagine a huge glacier, which is thousands of metres or hundreds of kilometres high and several metres wide.  

A glacier is always in motion and  changes slowly, moving from the mountain top down to the valley. During these slow but continuous movements, the glacier, here and there, rips down big parts of the mountain, which are blown with enormous force,   crumbled, swept away, mixed, rounded and smoothed, until round rock fragments of any size are created: the clastic rocks. This incessant activity produces also very small, microscopic pieces, which are moulded into sandy mud and then transformed to matrix.  When the glacier moves downhill, the glacier ice melts and moraines are created,  which are the glacier’s rubbish tip for mud and stones.  These stones, so called clastic rocks, are stuck in the mud/matrix and are covered with sludge.  

Then take extremely high pressure, terrific earth quakes, now and then, to shake forcefully the whole mass, the up and downs  of the  earth’s crust over millions of years…. and our Marinace is ready! 

Now you have to be a little more patient, while we are cutting and finishing the natural stone, and, immediately after, a top for your kitchen or a surface cladding for your bathroom will be ready and available. 

Don’t worry, you can choose between plenty of colours and you’ll find the right colour to match with your furnishing, your pavements and your coverings without trouble.
