“…Thus, the features of St and Sp facies of the FA4 together with the presence of brackish ichnofauna allow us to distinguish these channels from a purely freshwater fluvial channel (e.g. Longhitano et al, 2012;Pearson et al, 2012), and allow us to interpret these deposits as the subtidal part of the tidal channels in the central to inner part of an estuary (Table 2) Table 1), which is arranged in finning-and thinning-upward sheet bodies limited by irregular to sharp basal surfaces with thickness ranging from 0.5 to 1.7 m ( Table 2). Muddy intraclasts and thick mud drapes are sometimes present (Figs.…”

a b s t r a c tSedimentological, ichnological and paleontological analyses of the Early Miocene uppermost Monte Le on Formation and the lower part of the Santa Cruz Formation were carried out in Rinc on del Buque (RDB), a fossiliferous locality north of Río Coyle in Santa Cruz Province, Patagonia, Argentina. This locality is of special importance because it contains the basal contact between the Monte L eon (MLF) and the Santa Cruz (SCF) formations and because it preserves a rich fossil assemblage of marine invertebrates and marine trace fossils, and terrestrial vertebrates and plants, which has not been extensively studied. Ã 90 m-thick section of the MLF and the SCF that crops out at RDB was selected for this study. Eleven facies associations (FA) are described, which are, from base to top: subtidaleintertidal deposits with Crassotrea orbignyi and bioturbation of the Skolithos-Cruziana ichnofacies (FA1); tidal creek deposits with terrestrial fossil mammals and Ophiomorpha isp. burrows (FA2); tidal flat deposits with Glossifungites ichnofacies (FA3); deposits of tidal channels (FA4) and tidal sand flats (FA5) both with and impoverish Skolithos ichnofacies associated; marsh deposits (FA6); tidal point bar deposits recording a depauperate mixture of both the Skolithos and Cruziana ichnofacies (FA7); fluvial channel deposits (FA8); fluvial point bar deposits (FA9); floodplain deposits (FA10); and pyroclastic and volcaniclastic deposits of the floodplain where terrestrial fossil mammal remains occur (FA11).The transition of the MLFeSCF at RDB reflects a changing depositional environment from the outer part of an estuary (FA1) through the central (FA2e6) to inner part of a tide-dominated estuary (FA7). Finally a fluvial system occurs with single channels of relatively low energy and low sinuosity enclosed by a broad, low-energy floodplain dominated by partially edaphized ash-fall, sheet-flood, and overbank deposits (FA8e11). Pyroclastic and volcaniclastic materials throughout the succession must have been deposited as ash-fall distal facies in a fluvial setting and also were carried by fluvial streams and redeposited in both estuarine and fluvial settings. These materials preserve most of the analyzed terrestrial fossil mammals that characterize the Santacrucian age of the RDB's succession. Episodic sedimentation under volcanic influence, high sedimentation rates and a relatively warm and seasonal climate are inferred for the MLF and SCF section.Lateral continuity of the marker horizons at RDB serve for correlation with other coastal localities such as the lower part of the coastal SCF south of Río Coyle (~17.6e17.4 Ma) belonging to the Estancia La Costa Member of the SCF.

“…Tidal processes in the Pimenta Bueno Formation are characterized by intervals showing rhythmic bedding and tabular/tangential cross bedded sandstones with mud drapes in the foresets interpreted as tidal bundles, suggesting alternation of bed load and suspension load deposition linked to tidal cycles (Dalrymple & Choi 2007, Dalrymple 2010, Longhitano et al 2012. The presence of tidal processes in the upper portion of the Pimenta Bueno succession indicates connection to ocean and seas , most likely devoid of glaciation, representing an expressive interval of long term transgression.…”

“…Komposisi substrat pasir di lokasi penelitian terlihat cenderung tinggi yaitu berkisar antara 58,40 -96,20%. Tingginya substrat pasir dapat disebabkan oleh proses sedimentasi pada saat pasang surut berlangsung (Longhitano et al, 2012). Perakaran jenis Rhizophora spp pada formasi terdepan yang berbentuk tunjang dan rapat mampu menghalangi pergerakan partikel pasir dari arah laut menuju zona belakang pada saat air pasang, kemudian tertahan dan mengendap di zona depan saat surut (Besperi, 2011;Adi dan Murtiono, 2015).…”

ABSTRAKRegenerasi semai pada hutan mangrove merupakan salah satu bagian penting dalam proses suksesi sekunder. Penelitian ini bertujuan untuk menganalisis regenerasi alami semai pada areal terdegradasi di Taman Nasional Kutai, khususnya di Bontang dan Sangkima. Metode pengumpulan data yang digunakan adalah inventarisasi semai jenis-jenis mangrove yang tumbuh secara alami dan pengukuran kondisi lingkungan tanah dan air. Inventarisasi vegetasi dilakukan dengan membuat petak tunggal yang diletakkan secara sengaja pada petak tanaman rehabilitasi seluas 0,98 ha (Bontang) dan 1,04 ha (Sangkima). Sampel tanah diambil secara komposit dari lima titik pada petak pengamatan dengan kedalaman 0-30 cm dan 31-60 cm. Sampel air diambil dari setiap lokasi petak pengamatan sebanyak 200 ml. Hasil penelitian menunjukkan bahwa pada kawasan Bontang dan Sangkima tumbuh enam jenis mangrove, berturut-turut di kawasan Bontang terdiri dari jenis Acrostichum aureum, Scyphiphora hydrophyllacea, Rhizophora apiculata dan Ceriops tagal, sedangkan di Sangkima terdiri dari jenis Sonneratia alba, Rhizophora apiculata, dan Rhizophora mucronata. Distribusi semai mangrove untuk kawasan Bontang memiliki korelasi positif yang kuat dengan parameter lingkungan seperti tekstur tanah (Silt dan Clay), kimia tanah (KTK, N, C, Na, Ca), pasang surut, dan kimia air (salinitas, NO3, COD). Sedangkan di Sangkima memiliki korelasi positif yang kuat dengan parameter lingkungan seperti tekstur tanah (sand) dan kimia air (Mg, Al, pH, COD, BOD, DO, TSS). Untuk meningkatkan keberhasilan restorasi areal terdegradasi hutan mangrove di Taman Nasional Kutai, perlu memperhatikan aspek kesesuaian tumbuh tiap jenis mangrove berdasarkan kondisi lingkungan tiap tapak.Kata kunci: Taman Nasional Kutai, suksesi sekunder, komposisi mangrove, lingkungan (silt and clay), soil chemical (CEC, N, C, Na, Ca), tides, and water chemical (salinity, NO3 and COD). In other hand, seedlings distribution in the Sangkima area have strong positive correlation with environmental parameters of soil texture (sand) and water chemicals (Mg, Al, pH, COD, BOD, DO, and TSS). In order to speed up of the restoration in degraded areas of Kutai National Park mangrove forest, it was need attention to suitability aspects of each species based on the environmental conditions of each site. ABSTRACT Natural regeneration of seedlings in mangrove forest is an important part of the secondary succession process. This research aimed to analyze the natural regeneration that occured in degraded areas of Kutai
