Day 2 .Saturday 01. 08.
Departure from Belém to Salinas beach at 06.00 am (arriving in Salinas at 09:30 am).
STOP 1. visit the coastal sections of Pirabas Formation at the eastern shore of Pará state.
Two main localities will be visited, Maçarico and Atalaia beaches. In these outcrops are recognized, basically, four lithofacies: biocalcirudites, stratified biocalcarenite, no stratified calcarenite and biocalcirudite (lithological classification of the field, because the carbonate rocks actually are named through by microscopic analysis).The transgressive sequence of the Pirabas Formation in the cited localities is followed by the regressive siliciclastics of Barreiras Formation in considerable exposition.
NOTE: This will be a long day walking at the beach sections. Lots of drinking water recommended. Bring sunhat, long sleeves, boots, swim wear, sunblock etc.
Lunch will be offered (sandwich and water)
Day 3. Sunday 02. 08.
Departure from Salinas beach to São João de Pirabas city by bus. Arrival at São João de Pirabas and take a boat to visit the The Fortaleza Island Palaeontological Site.
NOTE: The time to cross from the territory to the island depends of the daily tidal time table.
STOP 2. “The Fortaleza Island palaeontological site”, located in São João de Pirabas northeastern of Pará state. It is considered the type section of the Pirabas formation and the Caribbean Province palaeogeographic southern limit. More details in http://www.unb.br/ig/sigep/sitio046/sitio046.htm. Return to Salinas beach in the same day.
The Fortaleza Island palaeontological site, located in São João de Pirabas borough, northeastern state of Pará, guards one of the most expressive occurrences of the Brazil Cenozoic marine sediments. It is considered the type section of the Pirabas formation and the Caribbean palaeogeographic southern limit.
The lithologic content include massive biocalcirudite, outcropping in two isolated localities (Ponta do Castelo and Ponta da Fazenda) separated by 2 km that constitute the base level of cliff relief. The sedimentary sequence has 3 meters of thickness and gray original color that by physical and chemical weathering change to yellowish. Associated with biocalcirudites are recognized coquinas, biohermitos, micrites and dolomicrites. The amount and varieties fossil contents, mostly in the biocalcirudite litofacies, which characterize a marine environment with neritic, warm, and shallow water, with normal, or to high salinity. The rich and diverse fossiliferous content possess foraminifera, porifera, corals, bivalves and gastropods mollusks, decapoda crustaceans, echinoids, fishes and mammals. The occurrence of some index fossils (mainly the gastropod Orthaulax pugnax, and the planktonic foraminifera Globigerinoides) located it, temporarily, in the lower Miocene. Also, these limestones that occur in Fortaleza island has a ostracofaune similar of this Caribbean region principally with ostracofaune of Brasso Formation of Trinidad.
Note: Lunch will be offered (sandwich and water)
In the afternoon return to the hotel in Salinas beach.
Day 4. Monday 03.08
7:00 – Departure from Salinas to Capanema city
STOP 3. The “B-17 Mine palaeontological and paleoenvironmental site”, SIGEP 121 (http://www.unb.br/ig/sigep/sitio121/sitio121.pdf), located in the Capanema district, northeastern of Pará State, guards the most expressive occurrence of the Brazilian Cenozoic Paleolagoon.
The calcareous “Mine B-17” (01º02’48’’S-47º09’18’’W) is located at the Capanema district, northeastern of Pará State. The access is granted through the road BR-316 which connects Belém city to the Capanema County. From this city one turns to the north by 17 km through of the PA-124, and enter to right accordingly the direction indicated by a road mark point to CIBRASA Mine, which owns the rights to explore the quarry. There are various benches opened for calcareous exploitation in Capanema ecofacies of the Pirabas Formation, and the B-17 Mine is one the major brazilian deposit that exploit the rocks for cement production. The quarry has 20 m of thickeness, close to the contact zone with 3 m of the Barreiras Formation.
The geologic section of “B-17 Mine” is composed by alternance of gray carbonatic lithofacies interbedded including marges, calcilutites, biocalcarenites no stratified, biocalcirudites and mudstones, as well as massive sandstones in the top of the section. This lithological variety distinguishes two categories of substrate firmness, firmgrounds and softgrounds and the shelled benthic fauna were adapted very good to these changes. The sessile benthic (Pectinidae, Ostreidae and Plicatulidae families of Bivalvia and encrusting bryozoans) are typical of firmgrounds. On the other hand the decapod crustaceans, vagile epifaunal and infaunal bivalves and gastropods live in soft substrates (softgrounds). The lithology and the dominance and diversity of paleoinvertebrates characterize the dominance of depositional environment of the Capanema ecofacies as tropical and restricted shelf/lagoon, with low energy and fluctuations of the sea level connected with open sea and estuarine system. The connection with open sea is suggested by planktonic foraminifera, centric diatoms, calcareous nanofossils and shark’s teeth, typical of the outer shelf environments. Also in the geologic setting are characterized some strata deposited in shallow sea environment that characterize typically marine conditions attesting the fluctuations of the sea level.
The great faunistic abundance of paleoinvertebrates in Capanema ecofacies of the Pirabas Formation, constituted by anermatypic corals, bivalves, gastropods, decapod crustaceans, balanomorph cirripedia and echinoids suggests eutrophic and well oxygenated environment with warm, clear and calm waters, low sedimentation rate, affected by waves (Fernandes, 1981; Ryland, 1970; Távora et al., 2002).
This will be a long day walking at the calcareous mine. Lots of drinking water recommended. Bring sunhat, long sleeves, boots, swim wear, sunblock etc.
Lunch will be offered (sandwich and water)
14:00 – Departure from Capanema to Belém City

3. Permian Ostracods from Paraná basin, Goiás State, Central Brazilshow
Chair: Geologist Henrique Zimmermann Tomassi (University of Brasília), assisted by M.Sc.
Cláudio Magalhães de Almeida (State University of Goiás).
For further information or in case doubt contact: hztomassi@gmail.com
In Paraná basin several fossils can be recovered from all over the Phanerozoic. In the south area of Goiás State, near the boundary with Mato Grosso State, Permian rocks, rich on marine and limnic ostracods, outcrops. As a result of Permian ostracods researches, the depositional system was interpreted as a shallow marine intertidal and lagoonal environments influenced by river influx. This region also reveals itself interesting due to the presence of the Araguainha dome, an impact crater with 40 kilometers wide (about 24.8 miles), dated as Late Paleozoic.
Minimum: 05 persons - Maximum: 15 persons
