The easternmost coherent tract of the pre-Mesozoic basement of the Carpatho-Balkanide belt is exposed in Tvarditsa Stara Planina Mountain. Two metamorphic units – the Lazovo and Shivachevo complexes as well as the Tvarditsa pluton were distinguished, as their ages are still not well constrained. Here, we present U-Pb (ID-TIMS) data for the Shivachevo complex and the Tvarditsa pluton, putting this information in the regional context of the late Variscan geodynamic evolution of the region.

El Niño 2015 is one of the strongest El Niño. Drought stress due to El Niño could affect oil palm performances. This study was conducted to determine rainfall pattern and oil palm performance in Sumatra and Borneo Island during El Niño 2015. Data employed in this study is monthly rainfall data, Southern Oscillation Index (SOI) January-December 2015, andoil palm performances. Pearson correlation between SOI and rainfall data was used to analyze rainfall pattern, while oil palm performances were observed based on morphological conditions. Result shows that southern part of Sumatra and mostly part of Borneo suffer from more dry spell, dry month, and water deficit such as 37-133 days, 3-5 months, and 349-524 mm respectively. Analysis of rainfall pattern shows that Jambi, South Sumatra, Lampung, Central, South, and East Borneo are significantly (r ≥ +0,60) affected by El Niño 2015. Oil palms in southern part of Sumatra and mostly part of Borneo are suffer from drought stressmarked by the emergence of more than two spear fronds, appearing of many male flowers, malformations on bunches, fronds tend to hanging down, and lower fronds tend to dry.
