Different Parts

At the Miette Hot Springs site, relict tufa stretches for nearly 500 m along the west side of Sulphur Creek valley and rises up to 30 m above the valley floor. The tufa, composed of low-Mg calcite, precipitated from waters discharged from a line of perched springs.14C dating of bone material embedded in the tufa indicates that tufa precipitation took place between ~4500 and 2500 years BP under cool and moist climatic conditions. The spring biota was dominated by filamentous microbes (mainly Phormidium and Oscillatoria), with fewer diatoms (including Cymbella), testate protozoans (including Quadrulella), ostracodes (including Darwinula, Heterocypris, Cadonia, and Cyclocypris), and various bryophytes. The ecological preferences of these microbes indicate that the spring water had near-neutral pH, was Ca, HCO3, and H2S–SO4rich, and emerged at 50–65 °C. Landslides disrupted the west wall of Sulphur Creek valley during and after tufa growth. The relict tufa is divided into six morphotypes that reflect variations in water flow down the steep and rugged flow path. Domal tufa is located around the spring vents, roll-over tufa developed where water flowed over sharp lips or structural barricades, vertical tufa formed where calcite was precipitate from water flowing down steep to vertical inclines, flat-banded tufa reflects precipitation on a gentle slope, and wedge-shaped tufa formed where more rapid downslope calcite precipitation caused a progressive decrease in slope. The tufa contains stromatolitic facies (including streamer, porous laminar, dense laminar) and nonstromatolitic facies (bedded, crenulated) that reflect variations in the biology, water temperature, and style of flow of different parts of the spring flow path.

Abundant Evidence

Many of the siliceous hot springs in Yellowstone National Park contain subaqueous, spinose siliceous precipitates up to 5 cm high that occupy shallow terracettes in siliceous terraced mound accumulations, discharge channels, etc. These siliceous "shrubs" are composed of opal-A with an arborescent or branching pattern and have strong morphological similarities to bacterial shrubs from carbonate-precipitating hot springs. Siliceous shrubs constitute a major precipitate style associated with discharge channel – flow-path facies throughout most of the 20 m of flow path at Cistern Spring, Norris Geyser Basin. They are found in siliceous spring waters ranging in temperature from 76.4 to 16.2 °C and pH from 6.0 to 7.4. At every scale, siliceous shrubs contain abundant evidence of microbial life in the form of bacterial body fossils and extracellular polymeric substances. The presence of relict organic constituents and bacterial morphological fossils indicates that the shrub fabric and architecture are dominated by bacteria, i.e., there is potentially a strong biotic effect on the precipitation process. Precipitation of opal in siliceous shrubs is very likely the result of either active bacterially induced precipitation or passive mediation through organic templates. On a larger scale, siliceous shrubs contain abundant evidence of former microbial activity in hot springs, thus they are good microbial biomarkers.

The Fall Creek Tufa is a relict, mid- to late-Holocene freshwater carbonate spring deposit that is formed almost entirely of calcite-encased Cratoneuron commutatum gametophytes. The spring is presently active, emitting 13 °C meteorically derived waters, but it is not precipitating calcite. Wood embedded in the youngest part of the tufa yielded a radiocarbon (14C) date of 310 ± 50 years BP. The oldest parts of the deposit could not be dated by radiocarbon methods because of a lack of embedded organics. The Fall Creek Tufa, however, probably began forming ~5000 years BP in response to the same wet climatic conditions that initiated calcite precipitation at Miette Hot Springs in Jasper National Park and the Cave and Basin Hot Springs in Banff National Park. The relict deposit is composed largely of calcite cements that were precipitated around the bryophytes, with lesser amounts of internal sediments. The tufa formed through a repeated four-stage developmental process that involved (I) encrustation, (II) encapsulation, (III) cavity occlusion, and (IV) diagenetic alteration. These stages were temporally and spatially variable. Although a young deposit, much of it has undergone extensive aggrading recrystallization, whereby crystal size has increased as adjacent calcite crystals were sutured together. Epifluorescence micro s copy shows that primary depositional fabrics were masked, but not destroyed, during recrystallization. Narrow ranges of δ18O (VPDB, Vienna Pee-Dee Belemnite standard) values (–18.4‰ to –17.7‰) and δ13C (VPDB) values (–1.2‰ to 0.5‰) indicate that the calcite was in isotopic equilibrium with the water that it precipitated from, and that diagenesis did not reset the stable oxygen and carbon isotopic compositions.

Strategic Factors

In northwest of Serbia in the meridians directions an elongated mountain range of Cer with Iverak and Vlasic stretches itself. On the north it goes down to Macva and Posavina, on the west to Podrinje, on the east to the valley of Kolubara, on the south to the basins and valleys of Jadar and upper Kolubara, which separate it from the mountains of Valjevo and Podrinje area. Cer mountain offers extremely good condition for development of eco-tourism. The variety of relief with gorgeous see-sites, natural rarities, convenient bio-climatic conditions, significant water resources, forest complexes, medieval fortresses, cultural-historic monuments, richness of flora and fauna, preserved rural environment, traditions and customs of local population, were all neglected as strategic factors in the development of tourism. This mountain?s potentials are quite satisfactory for the needs of eco-tourism, similar to the National Park of Fruska Gora, but it has lacked an adequate ecotourist strategy so far. This study aims to pointing to the potential and possibilities of ecotourist valorization of this mountain.
