19Pre-salt reservoir systems encountered offshore Brazil and Angola that consist of porous continental 20 carbonates are difficult to access because of the limited core material that is under concession. 21 Therefore, it is important to study comparable continental carbonate analogues, like travertines and 22 lacustrine carbonates, that possess similar porosity and permeability characteristics. The Budakalász 23Pleistocene travertines (Buda Hills, Hungary) have been studied from a sedimentological, geochemical 24 and reservoir point of view in order to understand their formation, petrophysical properties and 3D 25 reservoir architecture. 26The three-dimensional geobody architecture of the Budakalász travertines illustrates the potential 27 complexity of kilometre scale continental carbonate systems. Heterogeneous smooth sloping travertine 28 lobes consisting of terrace slope, smooth slope and reed facies, are covered by a lime mudstone 29 dominated, gastropod-and charophyte-rich marsh-pool facies. The observed facies represent a change 30 from a subaerial travertine to a palustrine to lacustrine system, reflecting the ceasing of the system due 31 to tectonic uplift. The dominant paleo-flow direction of the sloping lobes was towards the Danube 32 depression, with several subordinate flow systems identified. 33The Sr-C-O isotope geochemical signatures reflect travertine precipitation at ambient to superambient 34 temperatures from meteoric derived fluids with a mixed CO2 origin of the marine carbonate fluid 35 source rocks and an atmospheric or soil-derived component. Although the uniform signatures of the 36 stable oxygen and carbon isotopes, in addition to petrographic observations suggest partial diagenetic 37 isotopic resetting, the primary geospatial isotope trends seem to have been preserved. 38 2 A reservoir-oriented facies evaluation in the three-dimensional geobody frame of the Budakalász 39 carbonates based on porosity and permeability core plug analyses reveals their heterogeneous nature. 40Terrace, smooth slope and marsh-pool facies have considerable porosities of 5-15%, while the 41 porosity of the reed facies may reach up to 27%. Permeability of all facies is strongly anisotropic, 42 mainly controlled by a better connectivity along layer-parallel primary pores. 43The reconstruction of the 3D geobody architecture of the Budakalász lobe complex coupled to its 44 geochemical and petrophysical properties provides a unique dataset that so far was lacking. 45 46

“…The geotectonic studies focused on the relationships between bedded and banded travertine of the Çukurbağ-Denizli fissure ridge indicated that the banded veins were diachronous and migrated through time, suggesting a progressive fault zone enlargement in the footwall. Such a fault zone was characterized by polycyclic activity, with normal to transtensional kinematics, and was active during the latest Quaternary (Filippis et al, 2013). The formation of banded veins was coeval with bedded travertine deposition and strictly depends on fault activity due to the efficient conduits for thermal water migration, therefore highlighting the fundamental role of travertine fissure-ridges in reconstructing paleotectonic activity in a region (Brogi et al, 2014a(Brogi et al, , 2014b.…”

IntroductionTravertine deposits located 24 km northwest of Karakoçan (Elazığ) and 60 km southwest of Mazgirt (Tunceli) (Figures 1a and 1b) are on the Karakoçan Fault Zone (KFZ) and Pamuklu Fault Zone (PFZ) and segments of the faults. The terms 'travertine' and 'carbonate tufa' are often used indiscriminately. 'Travertine' is frequently used to refer to carbonate rocks formed from thermal water deposits on the earth's surface, forming various deposit morphologies such as cascades, apron and channel travertines, fissure ridges, plateaus, and towers (Pedley, 2009;Pedley and Rogerson, 2010;Fouke, 2011). According to Andrews (2006) and Capezzuoli et al. (2014), tufas are terrestrial carbonates that form under surficial open-air conditions in streams, rivers, and lakes. Tufa is a product of physicochemical and microbiological biomediation processes. Because tufas form under exposure to light, they contain microbial (bacterial and cyanobacterial) and sometimes other algal components; many tufas encrust higher plants that live on the margins of streams, waterfalls, and wetlands (Pentecost et al., 1997). Tufa carbonates precipitate at ambient temperature from the calcium-bicarbonate waters derived from the dissolution of carbonate bedrock. Travertines are freshwater carbonates precipitated by organic or inorganic processes from the resources of calcium-and bicarbonaterich underground waters (Guo and Riding, 1998). Rapid travertine precipitation initiates when the CO 2 gas within the outcropping waters is emitted to the atmosphere. These freshwater carbonates have an internal structure that frequently changes laterally and vertically. Many conditions, such as differences in the lateral and vertical facies, the position of the resource, the base topography, fluctuations in the amount of the waters storing travertine, and changes in the flow rate and direction of water, organic activities, and surface waters, are frequently encountered in travertine fields due to seasonal climatic factors and tectonic zones. Topography plays a determinative role in the development of facies and in the storing of travertines. The climatic changes' influence on algal growth and travertine precipitation, besides tectonic settings, may produce a significant effect on depositional geometry of the hydrothermal travertine formation. These conditions
